He just sounds like a very social child. My son who is now 3 is and always was very social and never shy. He would walk off with anyone which can be scary. He usually saw his cousin who is the same age once a week but it wasn't enough. Your son probably wants to get out of the house and do things. MyY son always wants to go. I would look into some mommy and me or in this case daddy and me programs. Both your husband and son would benefit and get him in a more social environment. He needs to learn how to socialize with other children on a regular basis. Then he will probably figure out how to act by watching other kids his age. I highly recommend the music and me program at buffalo community music school. My kids absolutely love it. It is great for their development and get them out of the house and around other toddlers.
