DS is 6 and normally plays lovely with "M" next door who is 7. We live in a lovely little estate that is very safe, has speed bumps etc and is generally a good environment for kids. We have a trampoline in our front garden which most of the kids play on and its just a lovely place.
However, a few streets away from our estate is a not so nice bit, its across a very very busy main road though so we weren't that fussed about it when we moved here.
Recently, there's a young lad, 'K' who comes across from the not so nice bit to our street to play, I can't blame him, as I said its a great place for kids. But he's 7, he crosses the main road and is round here for up to 6 hours at a time with no-one obviously checking up on him. Several times my dh has asked ds not to play with M, as we've caught him smashing bottles and just generally being a nasty little shit. I can't describe it, I don't like the wee boy, he's very very cheeky, "smirks" at me whenever I've asked him or my ds not to do something, he constantly jumps our fence despite being asked not to numerous times, then runs away laughing when i go out to reprimand him. grrrr he does my head in.
Anyway, to get to the point, M next door and K are in the same class at school, so quite often when ds and M are playing happily, K will turn up and all hell breaks loose. M's dad doesn't want him playing with this boy but his mum lets him because they are in the same class. She know's his mother, who apparently has had a child removed before and in her words is a bit of a "fuckwit" so I think she feels sorry for him. I did too, when we first moved here I let him come in to play as he'd been wandering the street in the pouring rain, but some money went missing from ds' bank so he's never been allowed in since, but of course I couldn't prove it was him and I would never accuse a child of stealing without proof.
We've told our ds loads of times we don't want him playing with him, but he says he's not, he's playing with M and K just keeps turning up. However, M wants to play with K so our ds tags along, he usually ends up fighting with K at some point.
I know I'm rabbling, but our son is by no means an angel, he's very very easily led and I have seen K try to get him to do stuff, so I really don't want him near him, he's trouble. But what can I do when M is playing with him and ds wants to play with M. Today i've brought him in away from K, he's upset, but he says himself K is a nasty boy and does horrible stuff, but I can't keep taking him away from M.
I'm just at a loss as to what to do. I'm very aware K is the way he is because obviously he is unsupervised most of the time and gets away with murder. he really is going to be a loose cannon when he's older and I don't want my son being involved with him.
Opinions?
