DS1 is 4.2 and generally a lovely, sparky little boy. He's very active and outgoing, but does have a bit of an issue with frustration- ie he gets frustrated and angry very easily.
Anyway, he goes to pre-school and has a good friend there. Friend lives around the corner and we see quite a bit of him- lots of visiting each other and sleep-overs etc. Friend's mother and I also on good terms and help each other with childcare each week.
DS has bitten his friend 4 times now. Each time seems to be borne of frustration- ie not getting his turn or other usual 4 year old squabble.
The 3rd time DS bit his friend it was apparently quite bad (it happened at pre-school but no adults saw the incident, however it left a mark and was on the face). After that incident, we punished DS- no dessert for a week and had a talk to his teachers and DS himself. DS knows that if he's feeling angry or frustrated and can't resolve the situation that he must ask an adult for help.
Unfortunately, friend's mother dropped DS off today and told me that DS had bitten his friend again today at preschool. They didn't involve the teachers. I asked DS if he did bite and he said he did and that his friend was trying to push in front of him up a ladder. I told him that it was not ok to bite and asked him what he should have done instead. He said 'tell a teacher'. Have punished him with no TV for today and again, no dessert for a week. Am wondering what more I can do to get the message across to him? He seems to know that it's wrong and that he should tell an adult if he needs help- so why does he keep doing it?
The second issue is that the friend's mother told me that if DS does it again, she will bite him back!! I'm completely aghast! She said this when she was dropping him off and I wasn't really concentrating and said something like 'oh right, well that will teach him' ,but after she left I stopped to think and have realised that I really don't think that's OK. It's hardly going to teach DS not to bite if his friend's parents are biting him back. I realise she's frustrated that the biting keeps happening (not every day- it's been 4 times over about 5 weeks), but now I'm feeling like I don't want to leave my son alone with her if she's going to bite him! Argh... sorry for long post- does anyone have any experience of this kind of thing?
