Don't misunderstand, I don't want to withhold information about his body's changes.. But age 10 seems a little young to start learning in this sort of detail. He's my only child so there's no older sibling to compare to.

I suppose by not attending class, the topic would be more mystifying and he would feel less comfortable with it. I don't want him uncomfortable.

Maybe the solution is for me to talk to him a little about it at home, tonight, so when it's covered in class, he will have more familiarity about it.
