“My goodnes you have a tendency to not understand stuff. “
I understand that by the age of 3 or 4, a child can get himself out of a carseat by himself, and get out of the car as well.
We are talking about infants and very young children who cannot help themselves in a deadly situation.
So your numbers are very inflated and you’ve inflated the amount of effort it would take to make a simple call.
Most parents call in themselves.
Not at all. not only is there the necessity for the call for the missing in your scenario, but there has to be some sort of roll call process checking the kids off against whose expected for the day to determine who is missing. You're not looking at the details. Enormous effort for totally miniscule benefit. Effort better spent on taking care of the kids rather than taking on the parents responsibilities.
