So I am a single mom and I have a friend who is also a single mom. Sometimes she bring her 8 year old son over to my house and he spend the night in the bed with my five year old son. The boys go to bed and we grownups get to watch a movie and hang out. Last night my five year old was in the room while I was changing his two year old brother's clothes. He told me that he was tickling his little brother's penis. I told him that penises are private and that he shouldn't touch anyone else's penis and that no one should touch his. He said, but my friend's eight year old asks him to touch his penis and he does. I was in shock. I made sure to tell him that I wasn't mad at him or his friend but that I just wanted to know what had happened. He said that when they go to bed my friend's son pulls down him jammie pants and asks my son to touch him. My son said that this has happened lots of times and that one time my friend's son wanted to touch his penis, too. I have a lunch date with my friend today and I am going to tell her what my son said. I am just so confused. I am wondering if her son was abused and that is why he did this, or if he was just curious. I am also wondering what I should do for my son at this time. He doesn't seem at all upset by it and I will make sure that the two of them are never alone together again, but does he need counseling? Probably, right? I am also concerned about my five year old now acting out at some point with my two year old. Any advice or info would be appreciated.
