While all that outdoor time sounds nice, I’d be concerned and unlikely to re-enroll my child…
First off, I’d be concerned with high staff turnover, as you say both his teachers are leaving the program. High staff turnover often points to problems, and it was a huge problem at my oldest child’s daycare. Even if their reasons for leaving don’t relate to something going on in the program, when good people leave, things change. You loved the pre-school* this *year, but it won’t be the same next year since his teachers are leaving.
Next, he’s four now, so he’ll be five by the end of the next school year. I’d expect that he will remember some things from his preschool years. I have memories of people and things from the preschool I attended when I was four. If you entrust the care of your child to this school, his memories may include things this teacher says or does. She may or may not be trying to actively promote an agenda, but whn she simply shares information such as what she did over the weekend, your child will hear of her lifestyle choices. It’s also fairly normal for moms to talk about their children and for pre-school children to be interested in babies. Your son may pick up on the fact that his “teacher’s baby doesn’t have–or need-- a father.” But that’s not true because her child does have a father, somewhere, (because that’s the way biology and human reproduction works.) Somewhere out there is her child’s biological father.
That gets to my last point: I’d be concerned about what this teacher lifestyle could relay to your young *son *about the role she thinks *adult males *have in society.
