JACKSONVILLE, Fla. -

A Jacksonville children's hospital is partnering with Safe Kids Northeast Florida to offer nationwide, online training for parents on car and road safety after two Indianapolis parents, in separate incidents left their young children in a vehicle during a heat wave.

On Saturday a 4-month-old girl died in Greenfield, Ind. and a 16-month-old girl in Fishers, Ind. suffered a seizure and was in critical condition after being locked in a hot car. 

The online courses offered by Wolfson Children's Hospital and Safe Kids Northeast Florida have three different levels of education, basic child passenger safety awareness and vehicle safety for transporting children with special health needs.

Safe Kids wants parents to know that when temperatures increase, it will be even hotter inside a closed door, even on a cool summer day. Temperatures inside a vehicle can become so hot children could easily suffer a heat-related illness, heatstroke or other life-threatening problems.

Parents should never leave children unattended in a car under any circumstances.
