Boy mom’s help please!!!

Gina

I have a 13 month old boy, about a month ago every time I change his diaper or give him a bath or pretty much any time he is naked, The first thing he does is grabs his private area and pulls, tugs, and squeezes hard on it. I’m sure he does it because he probably thinks it’s squishy and feels fun like a toy, but it kinda bothers me. My husband thinks it’s hilarious. ( typical guy 🙄) but I was wondering if this is normal? When I change his diaper I do give him a toy or a book to play with so he won’t grab himself but he throws the toy and grabs himself anyway. Will he grow out of it, at least until he’s older? I’m going to ask his pediatrician, but his next appointment isn’t until April. Also, he has a twin brother but he doesn’t do it.
