When my son was in first grade (1976?) I was in a casual conversation with one of the teachers here. At some point she was complaining because "some parents" expected her to "make sure my kid has his hat on" or "make sure she wears her mittens". I'll always remember her comment that "We're teachers, not babysitters".

Really? When I first put my daughter on the bus to kindergarten, she was still FOUR YEARS OLD!

Okay. Even knowing that the woman was speaking for herself and not necessarily the rest of the teachers, or perhaps even ANY of the others, from then on I kept my kids home when it was "dangerously cold" and they didn't cancel school.
