Biting 3 year old - long

[Fonzie]

Wondered if any of you experience Mums can help me as I'm at my wits end.
DS (3 years old) has bitten 2 children in the last 5 days after never really having done it before, especially not to children he doesn't know. Today's episode resulted in us leaving a good friend's house as soon as it happened without me even establishing the build up to it. I had previously warned DS that if anything like that happened and he was responsible then we would go home straight away.
I have a feeling that the other child today may have been taunting him as I had earlier heard him saying "Are you scared? Am I scaring you?" to DS but that's still no excuse for DS's behaviour today or on previous occasions. DS is also quite tired (it's the October break here so the structured day has disintegrated) but again, tiredness is no excuse. Please can you let me know of any way that I can minimise this happening as I'm at the point of being frightened of going out with friends and their children.

I think you're doing the right thing in removing him from the situation immediately after any incident.
Don't stop going out though, he won't learn unless he has the chance to make mistakes.
Just try to explain to the other parents whats happening and what you're going to do about it, so they're prepared if you need to leave.
Maybe think about having your child draw a picture of what the bitten child might feel, or ask him to talk about what he is feeling before he bites and what he could do instead to cope with that feeling. It might seem to go over his head at this stage but its worth a try, something might get through.

I just thought that it might be a good idea to keep a really close eye on whats going on between him and other children and try to intervene if you see him getting wound up. Maybe suggest something he can do, like stamping or shouting instead of biting.. yeah its not the most socially acceptable behaviour but its a whole lot better than hitting or biting.
