     FIELD OF THE INVENTION 
     This invention relates generally to breastfeeding training and more specifically to devices comprised of a doll and chest piece used for breastfeeding training. 
     BACKGROUND 
     Breast milk has numerous nutritional advantages as it contains the proper balance of amino acids, sugars and fats for the human baby, as well as vitamins, enzymes, and minerals that are best suited for the baby&#39;s intestinal tract and aid in digestion. Breast-fed babies have reduced risk of infection as the breast milk contains infection-fighting antibodies. Furthermore, the high cholesterol content in breast milk promotes brain growth in the baby. In addition to these health benefits, breast-feeding is the least expensive way of feeding the baby. 
     Despite the various advantages of breastfeeding, new mothers may still be unsure whether or not to breastfeed their baby. Issues such as discomfort, damage to the nipple, insufficient milk supplied to the baby and mastitis concern many new mothers when considering whether to breastfeed. Many of these issues can be remedied by proper placement of the baby relative to the mother&#39;s nipple. This proper positioning is referred to as “latch-on.” In general, proper latch-on is achieved when the mother&#39;s nipple is elongated and deep enough in the baby&#39;s mouth to reach the baby&#39;s soft palate. The soft palate is located behind the hard palate, which in turn is located behind the gums. Since the location of soft palate is quite deep in the baby&#39;s mouth, it is difficult for some mothers to position the baby to achieve proper latch-on. However, proper latch-on is necessary to optimize the breast milk drawn by the baby and to avoid undue pain, discomfort and injury to the mother. 
     Accordingly, to address expectant mothers&#39; myriad concerns and to teach proper latch-on, lactation consultants assist mothers by preparing them for breastfeeding and providing counsel on medical issues and other concerns that can arise in the course of breastfeeding a baby. 
     Methods exist that assess the quality of breast-feeding. For example, U.S. Patent Application US20080108882A1 discloses methods of assessing the health of a breastfeeding relationship that include clinical assessment. In another example, U.S. Patent Application US20080077042A1 discloses a method for quantifying breastfeeding between a mother and a baby. In another example, U.S. Patent Application US20080077040A1 discloses another method for quantifying breastfeeding between a mother and a baby. In another example, U.S. Patent Application US20080097169A1 discloses another method for quantifying breastfeeding between a mother and a baby. In another example, WO2008034194A9 discloses a method of assessing breastfeeding. In another example, WO2009093238A1 discloses a method of monitoring amount of milk consumed by an infant being breastfed by a breast, comprising determining variations in electric capacitance of the breast during breastfeeding, and correlating said electric capacitance variations to an amount of milk consumed by the infant. In another example, WO2008026088A1 discloses another method for quantifying breastfeeding between a mother and a baby. 
     Similarly, devices exist that provide assistance during breastfeeding. For example, U.S. Pat. No. 7,207,336 B1 discloses a compression device for use in helping a woman breastfeed an infant. 
     While these may be important in ascertaining the overall health of an infant, the impact of breastfeeding on an infant&#39;s health, or assisting the mother while breastfeeding, these references do not provide a means to teach the proper breast-feeding technique. 
     The use of dolls in the shape of patients is well known in the field of medical education and training. For example, dolls have long been used in cardiopulmonary resuscitation (CPR) training to assist trainees in learning the proper techniques in administering CPR. CPR trainees can press on the doll&#39;s chest and blow air into the doll&#39;s mouth to fill the doll&#39;s artificial lungs with air, and the dolls provide life-like responses to the trainee&#39;s actions. 
     A breastfeeding training doll can provide an effective means for lactation consultants to demonstrate proper latch-on positioning of the baby to expectant mothers. However, while the use of dolls in the shape of patients is well known in the field of medical education and training and devices that are capable of simulating biological functions, including the separate biological functions that may be associated with breastfeeding, such as suckling, for example, a device combining all the biological functions associated with breastfeeding does not currently exist. 
     Devices that are capable of expressing fluids, such as, for example, breast milk, from breasts are known. For example, U.S. Pat. No. 7,101,350 B2 discloses a breast cup for placing around a nipple and an areola area on a woman&#39;s breast, said breast cup being in the form of a truncated cone with a conical part and an approximately cylindrical part by the conical part of the cone, said cylindrical part of the breast cup forming first and second stimulating means that simulate the sucking and palate/tongue, respectively, of a breastfeeding child, and said conical part of the breast cup forming a third stimulating means that simulates the lips/jaws of a breastfeeding child. 
     In another example, U.S. Pat. No. 6,517,513 B1 discloses a pump having compression, suction, and heat adapted to optimize noninvasive extraction of intraductal breast fluid. 
     In another example, U.S. Pat. No. 4,772,262 A discloses a breast pump including a vacuum pump, vacuum hose, collection container, and a milk pumping flange for application to a woman&#39;s breast for removing milk from the breast. 
     In another example, U.S. Patent Application US20070210235A1 discloses a suction-based holder, comprising: a suction portion having a housing and a suction interface, the suction interface having an inner face and an outer face, wherein portions of the inner face of the suction interface are associated with the housing; a receptacle portion having a receiving channel defined therein; and a connector portion connecting the suction portion and the receptacle portion. 
     In another example, U.S. Patent Application US20050234370A1 discloses a system for expressing milk from a human breast, comprising: a control system adapted to be worn by a user; a massaging means adapted to be located posterior to the areola; an expression means adapted to be located in the vicinity of the areola; and containment means adapted to contain the expressed milk. 
     In another example, U.S. Patent Application US20030153869A1 discloses a breast cup for placing around a nipple and an areola area on a woman&#39;s breast, which breast cup is in form of a truncated cone with an approximately cylindrical portion by the truncated part of the cone, which cylindrical part of the breast cup forms first and second stimulating means that simulate the sucking and palate/tongue, respectively, of a breastfeeding child, and the conical part of the breast cup forms a third stimulating means that simulates the lips/jaws of a breastfeeding child. 
     In another example, U.S. Patent Application US20020193731A1 discloses a portable, hands-free and visually friendly breast pump for facilitating breast-pumping. 
     In another example, WO2009134274A1 discloses compact and hands-free human breast milk collection device that fits into a mother&#39;s existing nursing or standard brassiere. 
     In another example, WO2004026368A2 discloses a system for expressing milk from a human breast, comprising: a control system adapted to be worn by a user; a massaging means adapted to be located posterior to the areola; an expression means adapted to be located in the vicinity of the areola; and containment means adapted to contain the expressed milk. 
     Devices that simulate nipples are known. For example, U.S. Patent Application US20020139767A1 discloses a sipping lid for baby bottles. 
     In another example, U.S. Patent Application US20020063103A1 discloses a nursing bottle nipple for insertion past the lips of an infant and into the infant&#39;s mouth. 
     Anatomical training dolls are known. For example, the manikin disclosed in the publication located at http://www.laerdal.com/doc/42020286/Newborn-Anne.html discloses a manikin designed for skills training in neonatal resuscitation. 
     However, relatively few such training dolls have been developed to assist lactation consultants in their work. Artificial babies, such as the Lactessa™ doll are available to demonstrate the proper position for holding a baby. The Lactessa™ doll also allows a user to feel in the doll&#39;s mouth with her finger to determine the location of the hard and soft palate in the doll&#39;s mouth. 
     Also available is the device disclosed in U.S. Pat. No. 4,815,977. This reference discloses a breast-feeding trainer . . . to be worn over clothing in the teaching of nursing techniques. The patent claims “a breast-feeding trainer comprising a lightweight simulated human female breast having a simulated human nipple, and support means for positioning the simulated breast on the chest of a human wearer, said nipple being oriented for access thereto during breast-feeding training without removal of said support means by the human wearer.” 
     Also available is the device disclosed in U.S. Pat. No. 4,575,351 A. This reference discloses a training doll for prospective mothers, sisters, child attendants and the like is provided which includes a life-like torso having the approximate weight, size and appearance of a baby, preferably a newborn infant. 
     Also available is the device disclosed in U.S. Pat. No. 4,249,337 A. This reference discloses a breast feeding doll set comprising a mother doll having simulated breasts, first fastening means secured to the tip of each breast, a baby doll having a head and second fastening means secured to the head at the location of the mouth, said first and second fastening means being complimentary to each other for securing the baby doll to the mother doll in a simulated breast feeding operation and means for maintaining the arms of the mother doll in holding relation with respect to the baby doll. 
     Also available are toy doll sets such as the Bebe Gloton/THE BREAST MILK BABY®, a toy simulated breast milk feeding baby that does not require actual suction or latch-on but merely proximity to a pre-defined sensor in order to signify breast feeding, disclosed in the website located at http://www.dailymail.co.uk/news/worldnews/article-1204486/Meet-Beb/index.html, that are intended for children, consisting of a doll and chest piece. The Bebe Gloton/THE BREAST MILK BABY® system provides a doll that reacts by producing mouth sucking motions and sounds when the mouth of the doll is in proximity to the chest piece. 
     Also available is the doll disclosed in U.S. Patent Application US20090233518A1. This reference discloses an interactive toy doll where the doll interacts with the user by reacting to its own orientation and to pressure applied to its body or mouth . . . . The doll can be fed by placing a toy bottle in the doll&#39;s mouth. The doll will then react by making sounds of a baby sucking on a bottle. After a set period of time in which the doll has not been fed, the doll will emit crying sounds, as if the doll is hungry. 
     Also available is the device disclosed in U.S. Design Patent D576283S1. 
     However, these references do not provide feedback on whether the user is correctly positioning the doll for latch-on, nor do they interact directly with the user&#39;s own breast, nor do they provide an effective means to teach proper breast-feeding techniques. 
     Thus, the need exists for a breastfeeding training doll that will allow expectant mothers to practice breastfeeding and provides feedback to indicate when the baby achieves a successful latch onto the breast. 
     SUMMARY 
     The present invention provides and enables the following features, benefits and advantages, among others. In one aspect, the invention comprises a doll and a chest piece system allowing a user to simulate breastfeeding, where the doll provides feedback to the user on correct positioning of the doll relative to the chest piece and effective latch-on of the doll&#39;s mouth to the chest piece&#39;s simulated breast and nipple. 
     In an alternate aspect, the invention comprises a doll, where the doll provides feedback to the user on correct positioning of the doll relative to the user&#39;s breast and effective latch-on of the doll&#39;s mouth to the user&#39;s breast and nipple. 
     The Doll: One aspect of the invention provides a doll comprising a humanoid figure shape defining a head, neck and body, a power source, a mouth mechanism, a trigger located in the mouth mechanism which defines a mouth cavity, and a feedback system. The power source is connected to the trigger and feedback system. The feedback system receives and processes signals provided by the trigger, and depending on the trigger signal, outputs an alert to the user that indicates the doll is properly positioned for latch-on. The feedback system will be configured for certain trigger signals that indicate the correct latch-on position. When the feedback system receives such correct latch-on signal, the feedback system will output the alert. In an embodiment of the invention, the trigger further comprises a sensor. 
     In one aspect of the invention, the feedback system includes a suction mechanism located within the doll. In one embodiment, the suction mechanism includes a pump comprising a motor connected to a tube disposed through the neck of the doll, with one end of the tube connected to a suction ingress disposed in the mouth mechanism. In one embodiment, the suction mechanism operates similarly to electronic breast pumps and imitates the natural sucking rhythms of a baby. 
     In another aspect of the invention, the mouth mechanism is connected to the feedback system. In concert with the suction mechanism, the mouth mechanism will simulate mouth suction movements of a baby. 
     In another aspect of the invention, the mouth mechanism further defines a soft palate, hard palate, gums and a movable mouth. Each section of the mouth mechanism may be color coded for easy identification. In one embodiment, the mouth mechanism will simulate the movement of a baby&#39;s tongue against the baby&#39;s palate. 
     In another aspect of the invention, the head of the doll further comprises a transparent cheek area. The transparent cheek area allows a user to view the internal geometry of the mouth mechanism and the positioning of the simulated breast and nipple within the mouth. 
     In another aspect of the invention, the feedback system includes a light emitting diode (LED) disposed on the surface of the doll. Preferably, the LED is positioned on an area easily visible to the user when using the doll for breast feeding training, such as on the forehead of the doll. When the feedback system receives a sensor signal indicating proper latch-on position, the feedback system will trigger the LED to an “on” state. 
     The Chest Piece: One aspect of the invention provides a chest piece comprising at least one simulated breast having a simulated nipple, and a support means for the user to wear the chest piece over her chest and clothes. The at least one simulated breast and simulated nipple are shaped to resemble a lactating human breast. The at least one simulated breast and simulated nipple are malleable to the extent allowing for elongation during suction action by the doll, but of sufficient strength and resiliency to return to a relaxed state without significant damage to the chest piece. 
     In one aspect of the invention, the chest piece comprises a single simulated breast with a simulated nipple, adapted to be positioned over the chest of the user so as to simulate a natural human breast. In an alternate aspect of the invention, the chest piece comprises two simulated breasts with simulated nipples, adapted to be positioned over the chest of the user so as to simulate a pair of natural human breasts. 
     In one aspect of the invention, the at least one simulated breast and simulated nipple is composed of a synthetic human tissue analog. In one embodiment, the at least one simulated breast and simulated nipple is composed of a resilient material selected from the group consisting of rubber, silicone, plastic and combinations thereof. 
     In one aspect of the invention, the chest piece is attached to a brassier-type garment, adapted to be worn over the user&#39;s clothes. 
     In one aspect of the invention, the chest piece fits over the mother&#39;s actual breast in a manner that exposes and positions the mother&#39;s actual breast and nipple for practice utilizing the doll of the present invention. 
     The Doll-Chest Piece System: In one embodiment, the trigger in the doll&#39;s mouth mechanism is reactive to the simulated nipple on the at least one simulated breast in the chest piece. In an embodiment where the trigger comprises a sensor, the sensor has a sensing field in communication with the simulated nipple. 
     In one embodiment, when the simulated nipple is within a specified or pre-set distance relative to the sensor, the sensor sends a signal to the feedback sensor. The specified or pre-set distance of the simulated nipple relative to the sensor could be, for example, the distance corresponding to the touching of the simulated nipple to the doll&#39;s mouth mechanism. Alternatively, the specified or pre-set distance of the simulated nipple relative to the sensor could be the distance corresponding to the elongation of the simulated nipple that is the result of the correct positioning of the doll&#39;s mouth mechanism on the at least one simulated breast. One of ordinary skill in the art can readily determine the types and parameters for one, or more than one specified or pre-set distance, and can program the system of the present invention to respond differently according to the what specified or pre-set distance of the simulated nipple relative to the sensor is being sensed at any given time. For example, in one embodiment, when the simulated nipple is within a specified or pre-set distance relative to the sensor that corresponds to the elongation of the nipple that is the result of the correct positioning of the doll&#39;s mouth mechanism on the at least one simulated breast, the sensor sends a signal to the feedback system, which then outputs an alert to the user to indicate proper latch on. In one aspect of the invention, the feedback system will activate the LED disposed on the doll body upon receiving the proper latch-on signal from the sensor. 
     In another aspect of the invention, the suction mechanism in the doll will work upon the simulated nipple, causing the simulated nipple and simulated breast to elongate into the mouth cavity. When the simulated nipple is elongated into the doll&#39;s mouth cavity within a specified distance relative to the sensor, the sensor will send a proper latch-on signal to the feedback system and the feedback system will activate an alert to the user. In yet another aspect of the invention, in concert with the suction mechanism, the doll&#39;s mouth mechanism will also simulate sucking motions upon the simulated nipple on the at least one simulated breast. 
     In another aspect of the invention, the head of the doll further comprises a transparent cheek area allowing a user to view the internal geometry of the mouth mechanism. The transparent cheek area provides a view to observe the elongation of the simulated nipple as it is sucked into the internal mouth cavity of the mouth mechanism.

Although not shown in  FIG. 10 , the left simulated breast  207  and right simulated breast  209  each define a breast cavity similar to the breast cavity  206  shown in  FIG. 8   d.    
     Existing components may be utilized or modified in order to be employed as the breast or nipple components of the present invention. The choice of component can be readily determined by one of ordinary skill in the art. Components that may be utilized or modified for use in the system of the present invention may be found for example, in U.S. Pat. No. 4,815,977, or in U.S. Pat. No. 4,249,337 A. 
       FIG. 11  depicts one embodiment of the doll  100  with mouth mechanism  106  in open mouth position  40 , adapted to receive the simulated nipple  202  or alternatively, a mother&#39;s actual nipple. 
       FIG. 12  depicts a cross-section of the mouth mechanism  106  receiving and acting upon the simulated nipple  202  and simulated breast  201 . When doll  100  is within range of a reclining position, the mouth mechanism  106  assumes open mouth position  40  as shown in  FIG. 5( a ) , and the simulated nipple  202  is introduced into the mouth mechanism  106 , then suction device  114  (not shown in this figure) acts upon simulated nipple  202  through mouth mechanism  106 . The simulated nipple  202 , or alternatively, a mother&#39;s actual nipple, elongates under the sucking action and when the simulated nipple  202  (or actual nipple) is elongated to the extent it is in proper range of sensor  111  (not shown in this figure), the sensor  111  sends a signal to the feedback system  103 , and the feedback system  103  then outputs an alert to the user indicating proper latch-on position. In a preferred embodiment, the alert comprises the powering on of LED  115  disposed on head  105 .
