Reply to This is not going to sound good.

My feeling about this is, maybe this teacher is great but if you have this much stress about it, just ask to have your child moved. It isn't a judgement on this guy in particular, it is just what you need to feel safe during the day when your child is there. Yes, there are a lot of amazing male preschool teachers. But also yes trauma is real and it affects you. So just own that it affects you and do what you need to do to have a smooth path. I have never heard of a day care or preschool that wasn't absolutely full, and someone else will fill the spot.
