N.H.
I can tell you this... My son had a bit of reattaching and we asked the doctor about it. Our doctor is very laid back and said that it is no big deal. When he gets older and starts to get erections that it will take care of it self. He said that some doctors might want to do a procedure but he saw no reason to do so.
Good luck and don't feel pressured in to a procedure if that is what is suggested. Take some time and think about it. I think as he gets older and grows all will be good.
Good Luck!
