Not really an AIBU but I need advice mumsnetters!! I'm at the end of my tether! My DS (age 6, yr 1), has a 'friend' who is a mega mega bad influence and I don't know what to do. Please help!!!
They were in the same class in reception and I hoped they'd get split up this year but they didn't. This little boy (let's call him E) is really really naughty! Disobeys adults all the time, never listens, is mean to other kids, causes havoc, and uses horrible language (butt holes, cocks, and other choice words).
My DS likes him because he is fun and high energy, but whenever they are together my DS copies and joins in with this boy. Party today and my DS was really rude to me and had mega attitude because E was behaving like this (and his parents don't give a monkeys).
I have tried all kinds of tactics, from telling him he can't be friends with the boy (didn't work), to laying off completely, to talking to him everyday about the behaviour we expect and why not to copy E etc (we do this basically everyday).
I just feel so so sad. While I feel sorry for E and don't blame him (he's copying the language from someone himself I assume), I just hate his influence on my DS. My DS has lots of friends and attends many sports clubs outside school etc... and is always always lovely and polite and kind and sweet in all environments where E is not present. I've spoken to school and they r aware of E and split them up in lesson times, but I just don't know what else to do.
How can I stop my boy copying and playing with him???? I am really worried my DS will adopt Es attitude even when E is not present. 
Why does my DS not hang about with the 'nice' kids? He's really sweet
