My friend, who I've known for about a year, has two sons aged 5 and 7 and I have two aged 5 and 3.
The two five-year-olds were in the same class at school but started year 1 in different classes.
My friend's five-year-old is a bit of a nightmare when it comes to hurting other children. The last time we went to his house for tea after school, he dugs his fingernails into DS1's arm and kicked DS2 in the stomach. He's always been really cruel to DS2 and I have to keep a very close eye on him to make sure he doesn't get hurt.
Every time we see this child he does something nasty to either DS1 or DS2, or another friend of theirs who's in DS1's class. His mother 'tells him off' in a halfhearted way and threatens punishments (eg the boy won't have any cake after tea if he keeps behaving badly) but never follows through. So the boy knows he can do what he likes and there are never any consequences. She's said she doesn't mind me telling her son off, which I do, but there's only so far I can go. I can't impose punishments on someone else's son and also I feel it's up to her to address her child's behaviour.
The boy, as far as anyone knows, doesn't have any SN but I and lots of others (including his mum) feel he is very immature for his age.
So what do I do about this situation? I don't want to cut my friend off, because she doesn't have a lot of other friends and I think she's a bit despressed and I don't want to make her feel worse. But on the other hand I can't stand by any longer while my children (and others) are constantly hurt by this boy. Also it's difficult to see my friend without the children in tow.
It really is a difficult situation and any advice would be appreciated.
