My son is only 10 months and has always touched his wee-wee, even before his circumsion was completely healed( it was done at birth). Now every time I change his diaper he puts his hands down there and often smears his diaper rash cream everywhere. Often I just tell myself that's him being a Boy, lol:-)
I guess it is pretty normal. Well, now he has limited access becasue of the diaper so it takes advantage to explore his body when he is getting changed. Smart boy!
