     FIELD OF THE INVENTION 
       [0002]    The present invention relates to a device for reminding caregivers to alternate the resting body position of newborns in order to minimize positional plagiocephaly, also known as “flat spots.” 
       BACKGROUND OF THE INVENTION 
       [0003]    Positional plagiocephaly is a condition which causes the back and/or sides of an infant&#39;s head to become flattened through prolonged pressure from resting on flat surfaces (such as in car seats, cribs, strollers, and playpens). The condition primarily affects newborns because the skull bones are softest immediately after birth and harden over time. 
         [0004]    Positional plagiocephaly has become more prevalent in recent years due to the popular “Back To Sleep” campaign (BTS) promoted by pediatricians to minimize Sudden Infant Death Syndrome (SIDS). The BTS campaign instructs caregivers to lay infants to sleep on their backs and on firm mattresses. While BTS has succeeded in reducing the incidence of SIDS, it has exacerbated positional plagiocephaly because more babies are placed on their backs for prolonged periods of time on firm surfaces. 
         [0005]    Positional plagiocephaly can be minimized by frequently alternating the baby&#39;s resting position so that the baby&#39;s head does not rest on any one side for excessive periods of time consecutively, or repeatedly without alternating positions in between. The goal is to even out the pressures on the baby&#39;s head in order to maintain roundness and avoid flattening. This recommendation is endorsed by the American Academy of Pediatrics (AAP). In fact, many hospital Neonatal Intensive Care Units 
         [0006]    (NICUs), which care for premature newborns, instruct nurses to rotate newborns&#39; heads approximately every three hours. 
         [0007]    Despite such knowledge, the problem persists. For example, on Jul. 8, 2013, the Huffington Post published an article titled “Nearly Half Of Babies Now Have ‘Flat Spots’ On Their Heads.” The article cites a Canadian study published in the medical journal  Pediatrics  which found that “more than 46 percent of 2- to 3-month-old babies may have some form of the condition.” 
         [0008]    One of the causes is forgetful caregivers. New parents can be especially distracted and forgetful such that giving instructions alone will not sufficiently ensure the instructions are followed. With busy lives and other children and family members diverting their attention, parents with the best of intentions can still forget to alternate their baby&#39;s sleeping position. And even if they do remember to alternate their baby&#39;s sleeping positions, parents can still forget which position was chosen previously in order to choose a different position the next time the baby is laid to sleep. 
         [0009]    Some have attempted to solve the problem with handwritten journals or logbooks. But these methods also suffer the problem of forgetful caregivers. Since parents have a hard time remembering instructions in the first place, they also have a hard time remembering to manually log their baby&#39;s sleeping position each and every time the baby sleeps, which can be six or more times each day. And even if a log book is used sometimes, the process is cumbersome and likely to be disregarded with some regularity. 
         [0010]    Others have tried to solve the problem with specially designed soft pillows. These methods are problematic because the AAP suggests that no soft objects, specifically including pillows, should be left in a crib with a sleeping baby. 
         [0011]    Though often the problem may be mild, and pediatricians may recommend no intervention because the condition can correct itself with time, parents nevertheless can suffer emotional distress and guilt from knowing that the condition could have been avoided by regularly alternating their baby&#39;s sleeping position. 
         [0012]    But in other cases, intervention is advised. For example, in a not insignificant number of cases, custom molded helmets are used to reshape the baby&#39;s head which imposes additional emotional and financial costs on parents. Even here, however, there are issues. A New York Times article in May, 2014, titled  Helmets Do Little to Help Moderate Infant Skull Flattening, Study Finds , revealed that these helmets may not be useful. 
         [0013]    Accordingly, is it considered that there is a long felt need in the baby care field for a preventative solution to eliminate or reduce the incidence of positional plagiocephaly in a way which conforms with AAP guidelines. 
       SUMMARY OF THE INVENTION 
       [0014]    The present invention aims to provide parents and caregivers with an effective reminder to alternate their baby&#39;s sleeping position each time the baby sleeps. The primary function of the device is to allow a parent/caregiver to selectively indicate a first resting body position when the baby is laid to rest, and thereby remind the parent/caregiver to subsequently choose a different resting body position the next time the baby is laid to rest. Body positions may include, for example, “Back Left,” “Back Center,” and “Back Right.” While head position is the primary concern with preventing positional plagiocephaly, the present invention can also be used more broadly for reminding parents about overall body positions, such as “tummy time.” The terms “body position,” “head position,” “resting position,” and “sleeping position” are used interchangeably herein to mean the position in which a baby is placed for a prolonged period of time. 
         [0015]    A common embodiment of the present invention comprises a device for presenting to a user a plurality of suggested body positions in which to place an infant at rest at a first instance, and for reminding the user to choose a different one of the plurality of suggested body positions when the infant is placed to rest at a later instance. The device comprises a user interface for senting to the user a plurality of suggested body positions, said user interface comprising a display area to display said plurality of suggested body positions. The user interface further comprises at least one selectable indicator configured to allow the user to selectively indicate one of said plurality of suggested body positions (first body position) representative of the position in which the infant is being placed to rest at said first instance, whereby said selective indication of said first body position at said first instance reminds the user to place the infant in a second body position different from said first body position when putting the infant to rest at said second instance. This process of selecting and reminding can continue indefinitely. 
         [0016]    The user interface can comprise one or more selectable indicators which enable the user to select one of a plurality of suggested body positions. A single selectable indicator can be used in configurations featuring a single button, or a multiposition switch or knob. Multiple selectable indicators can be used in configurations featuring a plurality of buttons, each button representing one of the plurality of suggested body positions. Moreover, these selectable indicators can optionally illuminate upon selection. Another optional feature envisioned for the present invention is a controller, said controller being configured to cause the illumination of a selected indicator to blink after a predetermined amount of time (i.e., 60, 90, 180 minutes). 
         [0017]    Another possible configuration for the user interface can comprise graphical/textual representations of a plurality of suggested body positions and a button which causes a different one of the plurality of suggested body positions to illuminate each time the button is pressed. 
         [0018]    As an alternative to the user selecting one of the suggested body positions, a controller can automatically cycle through the suggested body positions by automatically illuminating a different one of said plurality of suggested body positions after a predetermined amount of time. 
         [0019]    Regardless of the specific embodiment, illumination can be used to enhance the reminding function of the device whereby the selectively indicated body position is indictaed by an illuminated lamp/LED which serves to remind the parent/caregiver to choose a different body position at a later time. This function can be enhanced by causing the illumination to blink after a predetermined amount of time to signal to the user that a new body positon should be chosen for the baby&#39;s next sleeping session. An optional memory module can be incorporated to store the most recently selected body position such that the device, if turned off and then on again, will default to the most recently selected body position. The memory module can also be used to maintain a log file of selected body positions and durations. 
         [0020]    Regardless of the specific embodiment, a controller, such as a microcontroller or discrete circuit, can be used to cause the selected indicator to provide a signal based on a predetermined parameter, where said parameter is programmed to correspond with a suggestion to the user to select a different body position (different from the previously selected body position) at a later instance. For example, in the case of illuminating indicators, the controller can cause the illumination to begin blinking after a predetermined amount of time (e.g., 30, 60, or 90 minutes) to provide a further indication to the user that the currently selected body position has been selected for at least said predetermined amount of time, thereby reminding the user to choose a different body for the baby&#39;s next sleeping session. 
         [0021]    Another embodiment of the invention comprises a first object with an indicating shape and a second object displaying a plurality of suggested body positions whereby one of the plurality of suggested body positions can be selected by moving said first or second object such that the indicating shape aligns with the selected body position. This embodiment can also employ illumination with an optional controller to cause blinking as discussed above. 
         [0022]    Another embodiment of the invention includes a wireless communictions module configured to communicate selected body positions (and associated times) with one or more mobile devices. One such mobile device could be a smartphone running an application which mimics the functionality of the device, as described herein, through software. This embodiment would allow a user to enjoy the functionality of the device anywhere the user takes the smartphone while also ensuring continuity between the device and the smartphone application. Such a software application can also be used to maintain a log of selected body positions and times, allowing the user to monitor cumulative times for each position. Using wireless communications, such as WiFi or Bluetooth, multiple reminder devices can remain synchronized so that multiple reminder devices can be controlled by the mobile application. For example, one reminder device can be attached to a crib in the nursery room and another reminder device can be attached to a playpen in the living room. Both reminder devices can be in wireless communication with a mobile device application so that any sleeping position selection made by the user will appear on both reminder devices simultaneously. Similarly, when a sleeping position is selected on one of the reminder devices, the mobile application will be updated as will any other reminder devices. Consequently, when the mobile application is properly synchronized with one or more reminder devices, a user may leave the home with mobile appplication in hand and continue using the reminder functionality in continuity with the home-based reminders which can re-synchronize with the mobile application when the user returns home. 
         [0023]    Additional embodiments of the invention include an analog or digital display for displaying the selectively indicated body position to the user. In the case of a digital display with touchscreen functionality, the display can also display the plurality of available body positions in addition to the selected body position, allowing the user to selectively indicate a chosen body position by touching the screen in the corresponding location. The digital display embodiments would also include a controller to control the display. 
         [0024]    Examples of digital displays include LED, LCD, OLED and TFT displays (with or without backlight), but it is understood that any type of digital display can be used. Examples of non-digital displays include backlit transparencies, illuminating buttons, dry-erase surface and marker, and moving, sliding, rotating or hinged objects representing the sleeping positions to be selected. It is understood that any means of allowing a user to selectively indicate one of a plurality of suggested sleeping positions, and thereafter identify which sleeping position was selected, can be used as a display. 
         [0025]    Another embodiment of the invention uses sensors to determine a resting baby&#39;s body position. The sensor can comprise a camera and image analysis software. The sensor can determine with which head position the baby is resting at any given time and, coupled with a processor and memory, record a log of head positions and cumulative times the baby rested in each position. The sensor can also enable the device to alert the parent/caregiver if the baby moves his/her head to a position which differs from the selectively indicated position chosen by the parent/caregiver. 
         [0026]    While the preferred embodiment enables the user to selectively indicate one of a plurality of suggested body positions, another embodiment can rely on a timer to cycle through a plurality of suggested body positions and thereby act as an affirmative instruction to the user which position to choose for the resting baby at any given time. 
         [0027]    The present invention also covers a method for reminding a user to alternate the resting body position of a baby. The method comprises (1) presenting to the user a plurality of suggested body positions, (2) enabling the user to select one of the plurality of suggested body positions representative of the position in which the baby is being placed to rest at a first instance (first body position) using a selectable indicator; and (3) providing a visual cue to the user indicating said first body position, said visual cue reminding the user to select, at a later instance, a second body position different from said first body position. 
         [0028]    The method for presenting to the user a plurality of suggested body positions can comprise a plurality of buttons, each button corresponding to a body position. It can also comprise a display area with graphical and/or textual representations of the suggested body positions, or a digital display depicting the same. 
         [0029]    The method for providing a visual cue to the user can comprise illumination associated with a selected body position, such as by lighting an LED or lamp. It can also comprise a digital display displaying a previously selected body position or a suggested body position. Generally speaking, the method of selecting a first body position at a first instance will visually distinguish said first body position from the remaining unselected body positions, and this visual distinction will serve as the visual cue to remind the user to choose a different body position at a later instance. 
         [0030]    The method for selecting a body position can comprise pushing a button, switching a switch or turning a knob. It can also comprise touching a touchscreen. It can also comprise moving a first object with an indicating shape (like an arrow or window) into alignment with a second object displaying a plurality of suggested body positions such that the indicating shape aligns with the selected body position. 
         [0031]    Another aspect of the invention which may be common to all embodiments is the presence of one or more attachment mechanisms. Examples of suitable attachment mechanisms include adhesive, hooks, clamps, snaps, Velcro, nuts and bolts, and adjustable straps for easy attachment of the device to the types of railings and handles commonly found on cribs, car seats, playpens, strollers and other places babies often rest for prolonged periods of time. Alternatively, a separate holster or pouch can be used which affixes to the desired location and holds the device in place. Each of the possible attachment means can be configured to allow easy removal and portability if the user wants to use the device in multiple places. The objective of the attachment means is to enable convenient attachment of the device in the types of environments babies are commonly laid to sleep (e.g., cribs, playpens, strollers, car seats, etc.). Accordingly, another desirable feature of the present invention is a transparent cover (hard or soft) to protect the device from body fluids emanating from the baby (i.e., vomit, urine). 
         [0032]    Any of the embodiments of the invention disclosed herein can be integrated into baby accessories (e.g., bags, blankets, bracelates, pillows, necklaces, carseats, strollers), clothing (e.g., hats, onesies, shirts, socks), furniture (e.g., cribs, playpens) and toys (e.g., mobiles, stuffed animals). The device can also be integrated into accessories for parents (e.g., bracelets, watches). 
         [0033]    Ideally, weight should be kept to a minimum, within the constraints of the overall configuration, to facilitate convenient attachment in a variety of positions and locations. For example, to make attachment inside, or on the perimeter of, a crib or playpen, minimum weight is desirable to minimize stress on the attachment means and to minimize potential harm to the baby if the device falls inside the crib or playpen. Therefore, lightweight construction is desirable for embodiments designed for such attachment. Accordingly, integrating the device into a soft cushioned housing can also be a desirable configuration. 
         [0034]    In another aspect of the device, a camera can be integrated into the device to stream audio/video signals to a remote monitor, including but not limited to a mobile computing device.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0057]    The present invention is a device and method for reminding parents and caregivers to alternate the sleeping position of a baby, as recommended by the American Academy of Pediatrics, in order to minimize positional plagiocephaly, commonly referred to as “flat spots.” 
         [0058]    It is understood by one having ordinary skill in the relevant art that all embodiments described herein requiring a power supply can use batteries, wall power, solar or other power source. Batteries can be replaceable and/or rechargeable by plugging the device into the wall through a mini-port (e.g., mini-USB). 
         [0059]      FIG. 1  illustrates an embodiment of the invention featuring a three-button user interface, comprising a plurality of illuminating buttons  004  which present to the user a plurality of suggested body positions. Buttons  004  can display either text alone (as shown), graphics, or text plus graphics. Housing  002  contains discrete circuitry and illumination means (shown in  FIG. 3 ) which enable each button to illuminate upon being pressed, while de-illuminating the other two buttons so only one button is illuminated at any time. It is understood by one having ordinary skill in the relevant art that such ciruitry is elementary to implement. The illumination of the selected body position reminds the user which body position was selected for the baby&#39;s previous sleeping session, which in turn reminds the user to choose a different body position for the baby&#39;s next sleeping session. 
         [0060]      FIG. 2  illustrates a perspective view of the embodiment in  FIG. 1  to demonstrate a preferred, relatively thin, form factor for the device to minimize weight and facilitate versatile attachment in various settings. 
         [0061]      FIG. 3  illustrates a cross-sectional view showing illumination  006  and circuitry  008  disposed within housing  002 . This view shows button  004  illuminated by illumination  006 , and how the buttons can be partially disposed within housing  002  so that the buttons connect with circuitry  008 . It is understood by one having ordinary skill in the relevant art that there are many different mechanisms for connecting buttons to circuits, so this element is not shown here for simplicity. Circuit  008  can also be configured with an optional processor (not shown) so that illumination  006  begins to blink after a predetermined amount of time (i.e. 30, 60 or 180 minutes). Another optional feature of this embodiment is a memory module to store the most recently selected body position. This memory function can be used to maintain a log of body positions and/or so the device can be turned off and then on again with the device defaulting to the most recently selected body position. It is understood by one having ordinary skill in the relevant art that implementing such a circuit, processor and memory module is elementary. 
         [0062]      FIG. 4  illustrates the same cross-sectional view in  FIG. 3 , but with button  010  in the pressed position. Notice that with button  010  pressed, illumination  012  illuminates and illumination  006  de-illuminates. When button  010  returns to its unpressed position, illumination  012  will remain the only source of illumination until a different button is pressed. It is understood by one having ordinary skill in the relevant art that implementing circuit  008  to enable the illumination scheme described herein is elementary. 
         [0063]    The embodiment in  FIGS. 1 through 4  are not limited to the construction of detail shown there or described in the accompanying text. As those of skill in the art will understand, the embodiment can be fabricated from any suitable material in any suitable dimensions using any suitable components which allow a user to select one of a plurality of suggested body positions at a first instance, and subsequently remember to select a different one of said plurality of suggested body positions when placing the baby to sleep at a later instance. 
         [0064]      FIG. 5  illustrates an embodiment of the invention featuring a display window user interface with sliding selectable indicator which allows the user to select one of several suggested body positions by moving tab  102  which is attached to internal object  108 . Housing  100  contains a display window  104  through which the user can view a portion of internal object  108  displaying a plurality of suggested body positions. By sliding tab  102  up or down, the user can cause a different one of the plurality of suggested body positions to be displayed through display window  104 . 
         [0065]      FIG. 6  illustrates a side-view of the embodiment in  FIG. 5  to further show how tab  102  is attached to internal object  108  which is disposed inside cavity  110  of housing  100 . By sliding tab  102  up or down within slot  112  in housing  100 , object  108  can be repositioned inside cavity  110  such that a different body position displayed on object  108  can be viewed through window  104  as shown in  FIG. 5 . It is understood by one having ordinary skill in the relevant art how to manufacture an embodiment as depicted in  FIGS. 5 and 6  with appropriate dimensions, tolerances and materials so that object  108  stays firmly in place after the user moves tab  102  up or down. 
         [0066]      FIG. 7  illustrates another version of the display window user interface embodiment, this time in a circular configuration. A user of this embodiment can select one of several suggested body positions by sliding tab  204 , which is attached to display wheel  202 , along its arching range of motion. This embodiment comprises a cover wheel  200  and display wheel  202 . Axel  206  (a rivet or other type of rotation-enabling fastener) allows cover wheel  200  and display wheel  202  to rotate around a common axis. Display wheel  202  displays a plurality of suggested body positions, each of which can be viewed by the user through display window  208  in cover wheel  200 . For example, when the user wants to select the sleeping position “Back Center,” the user can slide tab  204  in either direction until s/he sees “Back Center” displayed in display window  208 . 
         [0067]      FIG. 8  illustrates how certain suggested body positions displayed on display wheel  202 , such as belly positions which pediatricians suggest parents should closely supervise, can be associated with special instructions to be displayed through a second display window  210  (special instructions can also be displayed through the same display window as the suggested body position). For sleeping positions without special instructions, such as in  FIG. 7 , the second display window  210  will remain empty because there will be no special instructions displayed on the corresponding portion of display wheel  202 . For sleeping positions with special instructions, such as in  FIG. 8 , the special instructions will appear in display window  210  because they will be displayed on the corresponding portion of display wheel  202 . 
         [0068]      FIG. 9  illustrates another version of the rotating wheel user interface embodiment introduced in  FIG. 7 . This embodiment adds a time wheel  214  which allows the user to select the time of day that a sleeping position is selected. Time wheel  214  rotates independently around the same axis  206  as cover wheel  200  and display wheel  202 . The user can rotate time wheel  214  so that the time of day aligns with indicator  216 . By selecting a time of day each time a new sleeping position is chosen, the user can know when a new position should be chosen at a later instance. For example, if the user lays the baby to sleep and selects the “Back Center” position at 12 PM, and then lays the baby to sleep again at 6 PM, the user can observe that the “Back Center” position was chosen for the baby&#39;s last sleep session and therefore choose a different position for the baby&#39;s next sleep session. 
         [0069]      FIG. 10  shows the rotating wheel embodiment with time wheel introduced in  FIG. 9 , but with AM/PM time markings instead of military time (e.g., 0-24 hours) markings as in  FIG. 9 .  FIG. 10  also illustrates the special instruction feature introduced in  FIG. 8 . 
         [0070]      FIG. 11  illustrates a side exploded view of the embodiments in  FIGS. 9 and 10  with an optional mounting piece  218 . Axle  206  is shown in a two-piece configuration, but a single piece rivet or other type of rotation-enabling fastener can be used to hold the pieces together and provide a common axis around which pieces  200 ,  202  and  214  can rotate. 
         [0071]    The embodiments of  FIGS. 7 through 11  can be constructed with paper, laminated paper, plastic, or other lightweight material. Additionally, a mounting piece can be used—such that the display wheel is sandwiched between the cover wheel and mounting piece—to facilitate attaching, hanging or mounting of the device. 
         [0072]      FIG. 12  illustrates an embodiment of the invention featuring a multi-position switch user interface which allows the user to select one of several suggested body positions by sliding a multi-position switch  304  into a position which corresponds with one of a plurality of suggested body positions  308 , the plurality of body positions being indicated by text (and/or images) displayed on housing  300 . By sliding switch  304  along its range of motion  306 , the user can select a different sleeping position, such as “Back Left” as indicated in  FIG. 12 . An optional LED  302  can be configured to illuminate each time a different position is selected. Additionally, LED  302  can be configured to blink after a selected body position has been selected for a predetermined amount of time (e.g., 30 minutes, 45 minutes, 1 hour, 3 hours). As in  FIGS. 1 through 4 , it is understood by one having ordinary skill in the relevant art that implementing the circuitry necessary for the illumination scheme described herein is elementary. 
         [0073]      FIG. 13  illustrates a perspective view of the embodiment in  FIG. 12  showing internal construction comprising illumination  310  which illuminates the user-selected body position to stand out against the unselected positions. A lamp (or LED)  310  disposed inside housing  300  behind each selectable body position can be illuminated upon the user placing switch  304  in the position corresponding to said body position.  FIG. 13  also shows how the sleeping positions can be displayed on multiple surfaces of housing  300  to facilitate viewing from multiple angles. If affixed inside a crib, the user can more easily see the sleeping positions displayed along the device&#39;s top surface. If affixed to the railing, the side displays will be more visible. 
         [0074]      FIG. 14  illustrates a perspective view of an embodiment adapted for attachment to the railing  406  of a crib or playpen. This embodiment has a 5-button user interface. Buttons  400 , each one corresponding to a user-selectable suggested body position, are configured along an inclined surface of housing  404  for easy viewing and access to a typical adult user standing at the side of a crib or playpen. LED  402  (one on each button) can illuminate upon the pressing of a button, and optionally blink after a predetermined amount of time, as discussed previously. 
         [0075]      FIG. 15  illustrates an embodiment of the present invention featuring a rotating knob user interface, which allows the user to select one of a plurality of suggested body positions by rotating selector  508 . The user can select one of the body positions by rotating selector  508  such that indicator  506  aligns with one of the body positions  502  (“Back Left”, “Back Center”, “Back Right”) displayed on body  500 . The selected position can be further indicated by an optional LED  504  and/or optional digital display  510 . 
         [0076]      FIG. 16  illustrates a perspective view of an embodiment of the present invention featuring a digital display and multi-button user interface. This embodiment comprises a digital display  602  communicating a body position corresponding to the button  604  selected by the user (illustrated here as a series of buttons; but switches, sliders and knobs can be used). Optional timer  608  counts the time a given position is displayed. An optional LED  606  (one for each button) illuminates when the corresponding button/position is selected, and optionally blinks after a predetermined amount of time. Housing  600  contains the aforementioned components and an optional attachment mechanism (not shown) which allows the user to affix the device within the immediate vicinity of the baby&#39;s resting/sleeping environment (e.g., inside of a crib, railing of a playpen, handle of a car seat or stroller). 
         [0077]      FIG. 17  illustrates a perspective view of an embodiment of the present invention featuring a digital display and sliding multi-position switch user interface, similar to the embodiment in  FIG. 16 , but with a sliding multi-position switch  604  instead of individual buttons. 
         [0078]      FIG. 18  illustrates a schematic representation of the internal components of the embodiments in  FIGS. 16 and 17 . Buttons  710  correspond to the different body positions. When the user selects a button, microprocessor  706  sends the corresponding information from memory  704  to the digital display  702  such that the selected body position is displayed. Simultaneously, microprocessor  706  begins counting the time that the current position is displayed. The elapsed time can be displayed on digital display  702 , a separate timer  712 , or not be displayed at all. The LED  708  corresponding to the selected button  710  illuminates solidly upon being pressed by the user, and optionally begins to blink after a predetermined amount of time in order to inform the user that said amount of time has elapsed since the button was pressed. If the user selects a different button  710 , the previously lit LED  708 , whether solid or blinking, ceases illumination and the LED corresponding to the new button illuminates and the timer resets. The aforementioned functionality is controlled by the microprocessor, as programmed by a person having ordinary skills in the art of basic electronic controllers, and/or through discrete circuitry as configured by a skilled electrical circuit designer. 
         [0079]      FIG. 19  illustrates an embodiment of the invention featuring a display window user interface, comprising a first object  800  displaying a plurality of suggested sleeping positions  804 , and a second object  802  with a display window through which the sleeping positions displayed on said first object  800  can be viewed. Alternatively, instead of a display window, second object  802  can feature a conspicuous indicating shape, such as an arrow or triangle, to point out the selected body position. By sliding second object  802  in relation to said first object  800 , the user can align the window (or indicating shape) with the selected body position, and thereby selectively indicate a first body position when laying a baby to rest at a first instance. This indication then serves as a visual cue to remind the user to subsequently select a second body position different from said first body position when laying the baby to rest at a later instance. 
         [0080]      FIG. 20  illustrates an alternative embodiment of the invention comprising a main housing  950  with illuminating buttons  954  disposed within said housing, wherein housing  950  is configured with a hole which allows the housing to be hung on a circular hook  952 . The purpose of this figure is only to illustrate one of many possible attachment mechanisms for the device. 
         [0081]      FIG. 21  illustrates a side view of the embodiment in  FIG. 20  demonstrating how housing  950  can be hung on circular hook  952 . 
         [0082]      FIG. 22  illustrates another embodiment of the present invention featuring a screw-clamp attachment mechanism. A main housing  956  (with buttons disposed within) is configured with a bolt  958  extending from the rear of the housing such that a user can attach the housing to a structure by screwing nut  960  onto the bolt such that the housing will be firmly held in place. The purpose of this figure is only to illustrate one of many possible attachment mechanisms for the device.
