A 14 year old boy is old enough to know it is wrong to do this to his younger sister it is appropiate you get some help and he definatly realise it is wrong....The younger child has to be protected., if she awoke and saw him at 14 year old trust me it would have an effect on her, so ask his Dad to work out how you go about it,.
Mrdibs - If you suspect some sort of sexual abuse that your son may have endured then by all means, get him some counseling! However, it is completely normal for siblings or childhood friends to "explore". The fact that he did it at nite while she was asleep should not concern you as much as you think it should. 14 year old boys will use anything to stimulate themselves, and they are not thinking about appropriateness. There minds are on one thing and one thing only. Don't make more of it than it is. Your son is not some pedophillic monster, he's only an adolescent boy. Do however, ask your daughter if he's done anything that's made her uncomfortable - don't scare her, though! If you scare her, she may interpret something as innocent as a sibling punch to the arm as inappropriate. I would however, keep a good eye on your son and certainly not allow him to be around his little sister while she sleeps. Above all else, don't make your son feel like he's an abhorant monster. Remember, he's just a little boy discovering his sexuallity! Explain to him that touching himself is perfectly acceptable, but that he should do it in private and certainly no longer use his sister to satisfy himself. He'll find other outlets now that you've shown him the error of his ways. Adolescent counselor hoping this helps. p/s Are seperate bedrooms a possibility? This would help a great deal! Good luck
I would seek counseling immediately. I would also find out if he's ever done anything like that while she's been awake, and if so, I would seek counseling for her as well. I will keep your family in my prayers!!
Totally inappropiate speak to him severely about it, make sure he has no access to her at night, supervise him, talk to him ask his Dad to do the same..
