CROSS REFERENCE TO RELATED APPLICATION 
     This patent application is related to and claims priority from U.S. Provisional Patent Application Ser. No. 61/040,931 filed Mar. 31, 2008. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates, in general, to child safety devices and, more particularly, this invention relates to a child safety device to help prevent child from being forgotten and left in vehicles. 
     BACKGROUND OF THE INVENTION 
     Prior to the conception and development of the present invention, and as is generally well known in the prior art, parents and caregivers through forgetfulness leave young children alone in parked vehicles. This creates a health and safety risk for the child, especially if the outside temperature is particularly hot or cold. These dangers have been known to cause hypothermia, hyperthermia, dehydration or even the death of young children. Additionally, the forgetful parent or care giver could face criminal charges for leaving a child unattended in a vehicle. 
     SUMMARY OF THE INVENTION 
     The present invention, in one embodiment, is a belt like device comprised of two sections connected together with magnets. The free ends of the two sections can be equipped with clips for securing each section to either child or caregiver. Additionally, it is foreseen that a free end could be attached to a child&#39;s car seat instead of the child directly. It is envisioned that almost any securing means could be used for securing the free ends to either child or caregiver, including using straps as the sections and simply tying the free ends to child and caregiver. When the caregiver gets out of the vehicle the magnets and their respective sections separate, and a tune, tone, song, or some other audible signal is played through a speaker on the device. The audible signal could be activated by the use of a magnetic sensor or magnetic switch. The audible signal would alert and remind the caregiver that a child is still in the vehicle. 
     Additionally, the belt like device creates a conscious and physical connection between caregiver and child, aiding in reminding the caregiver of the child&#39;s presence in the vehicle. 
     OBJECTS OF THE INVENTION 
     It is, therefore, one of the primary objects of the present invention to provide a child safety device that alerts a caregiver of a child in the vehicle they are exiting. 
     Another object of the present invention is to provide a child safety device with a physical and visual connection between child and caregiver. 
     Still another object of the present invention is to provide a child safety device that audibly alerts a caregiver of a child in the vehicle they are exiting without waking the child if they are asleep.
