In a public service announcement, ABC News warns about leaving babies and young children in your car on a hot day. As a way of reminding you that your baby is in the backseat, they suggest placing something important in the backseat along with the baby. I adopted my son at seven, so I have never had a baby but I can't think of anything that would be more important than the baby.
Walmart has signs on the entrance doors reminding parents not to leave their babies in a hot car. How could anyone ever forget their baby??????
