Yes, erections are normal on babys and boys of all ages. The difference in what I am referring to, (see LKT 4 Year Old Son - Puberty)is due to runaway bone growth/growth hormone due to prolonged mismanagement of OHP levels. When left untreated as was my sons, they begin to go through a real type of puberty! Not the cute one that we giggle at when they are babies or two or three years old. Been there, done that one. That one is usually due to some kind of sensitivity in that area and goes away as quickly and quietly as it came. The one I first posted about is very close to the one that teenagers experience at 13 - 15 years of age +/-. My son became very aware (at 4 years old) that his body was going through some changes. We are very close and talk alot about everything, but this proved to be very difficult for him (not to mention me). He experienced the body odor of a football player (after the game), his penis enlarged (as if it wasn't large enough already), he began to develop fuzzy hair in places I don't think I need to explain and he was having constant erections simply from looking at a picture in a McCalls magazine. He developed interest in girls/women that he couldn't understand. He would try to reach out to me and talk about it but then all the sudden he would cry with frustration because he couldn't explain it in words to me. By that time he wasn't the only one crying. I could tell he was feeling like he had a crush on these girls but he was ONLY FOUR YEARS OLD and didn't have the maturity to make sense out of it all. Don't worry, from what I understand it doesn't happen to all boys with CAH. It is due to the extreme excess growth hormone his body is dumping due to his meds not controlling him. As I had stated in my earlier posting, the erections have subsided since our switch to the pill form of Cortef and his OHP levels have dropped substantially. We are still left however, with a little boy who's personallity has changed due to his visit to the "other side" of manhood. He is drawn to "sexy" things and made a rapid exidus from children's videos to ones with real people (preferably girls)in them but still in the P - PG level. I am looking into Precocious Puberty to see if this is similar to what he is going through right now. Please feel free to share with me any similar experiences or just a sympathetic ear as they say. I'm a bit heartbroken to say the least but I know we will get through it. I would have 10 more children even if they had CAH if they were all like my son. I just want to help him in any way I can. God knows that the deck is stacked against them from the start and we all want to do whatever we can to support these kids physically and emotionally. Looking forward to your responses.
