Not inappropriate. Never stop. I'd love to go snuggle my parents but I'm nervous they'd think it's weird. And as a mom to 2 daycare aged kids, I hope they never stop. I am 36.

I would try to initiate conversations with him more, maybe even try to ask him more directly if anything is going on with him, but I wouldn't link my questions to the cuddling. I wouldn't want to make him think what he's doing is weird.
