Some child safety advocates in Florida are calling for special vehicle alarms following the death of a 2-year-old strapped and forgotten in her car seat for nearly 6 hours in the back of a Delray Beach daycare center van.

A few other states already have laws mandating that all vehicles from childcare providers that transport six or seven (depending on the state) or more passengers have a child safety alarm system that prompts the driver to inspect all seats before leaving. Mary Sachs, a state representative, said she will sponsor a bill next spring requiring the alarms in Florida.
