Please, God, make it stop.
There is no reason. None. No excuse. None.
Put your child first. Rewire your brain. Or something. This dear sweet innocent child you have has no reason for being except for both parents, make it count. PLEASE. Nothing on earth is as important as that little breath of life in that car seat. Not your schedule. Your effin cell phone. Your work. If you're exhausted find someone to care for that child while you sleep. Stop working until you get your act together. Call each other to make sure your child, who depends upon you 100%, has been taken proper care of. And yes, even though it should NOT be our responsibility as providers or educators, if your day care child does not show up, follow up on them!!! It might be just enough to stop this terrible tragedy from happening. Even just once. So what if it takes you a minute?? One lousy minute is not enough to upset your whole day or routine.
PLEASE change something within your life, to make your child/ren #1. Because it CAN happen to you. God forbid, it can happen to you. Don't let your own living breathing child become another hot car statistic.
There will be no take backs. Don't be selfish. Don't be in denial. Plan, be proactive, concentrate and think.
