it's around 13 boys start looking for a role-model, maybe your son thinks he's found his.
have you asked him why he likes this boy?
have you told him how you feel and why?
that it's ok for his friend to act the way he does because that's how it is in his house but not your son and not in your house.
as a mum and childminder i've always tended to lean toward distraction instead of punishment.
what kind of distraction could be used here?
wonder if he's the kind of boy who would like group activities? sports? etc. keeping him busy outside school so he won't have time for the other boy.

hmmm... my sister going through same thing with her 15 and 22yr old, regarding boyfriend.
again have you told him how you feel and the effect he's having on you and your relationship with your boyfriend?.
have you asked him how he feels about your boyfriend?
can you not reach an agreement about what you both expect of each other when your boyfriend is at yours.

being a single mum who's son is only 6 i know nothing about teenagers but have only said how i would handle it if it happened to me. whether it will work or not when my time comes i don't know but i'd like to think so.

good luck to you all, hope your family comes together soon.

Thanks 4 yr advice sounds good to me. I am very close to the children generally and we talk alot but sometimes there just isnt enough hours in the day or enough of me to go between all three of them and work too. Thanks again
