My son is about 2.5 year old and it all started around 1 month ago, he seems to like touching his genital and rubbing it against either my leg or the floor. At first it lasts for 1-2 hours and I can easily distract him, now it becomes his habit and he cannot stop unless I pull him out to do something else. If I leave him alone, he can continue doing it without stopping. This really bothers me, he seems to enjoy it so much. Have any parents out there observed this kind of behaviour on their toddlers?? How long will it last or will this ever go away when they grow up?? In fact, I took him to see a doctor and that doctor only replied that it is completely normal and didn't offer me any suggestions to stop this except only to distract him everytime. Please share with me your experiences. Thanks a lot.
