My son turns 9 next month and I think he's already going through puberty. We've gotten notes home about his smell. He needs deodorant badly. He now has bad acne and some facial hair. My ex told me he accidentally walked in on our son and he now has a full bush. He only told me he's already experiencing wet dreams. They talked a little because he's asking why he's the only one in third grade with hair and bumps on his face. I feel this is so young. Especially for a boy since boys typically go through puberty later than girls.
