| Parents of teen boys
I suspect my son is about to enter the big change, he has CF so physically he is behind a bit from other of his age, he has been taking growth hormones for the last month. Today when he had his shirt off, I noticed that his nipples where slightly swollen, and he commented about his leg hair getting darker in color. What other things should I expect? He already has a deep husky voice and sounds much older than he really is, I can't imagine it getting much deeper. This is all brand new to me, he is my oldest, and I have another son who is a few years younger than him. TIA
