Unreal.
I pulled my son from his 5th grade class in our Christian school the day they were going to explain the female body and the monthly cycles to all of the 10 year old boys.
I thought THAT was completely unnecessary. I can’t imagine leaving kids in the hands of these “experts”. Grab your kids and run.
The problem with that strategy is this. The next day when your son DID attend school, all of his 10yr old friends explained all that to him anyways. Just like the 1 or 2 ‘liberated’ first graders invariably ruin Santa Claus, Easter Bunny and Tooth Fairy for the rest of the kids.
