This was first incident but I really don't want it to become a ongoing behaviour. Ds1(12) said no to ds2 (4) playing on ds1's phone so ds2 bit him, hard! I told ds1 that I was cross and that you shouldn't bite and grim to say sorry to ds1 and sat him down for 4 minutes while I sorted kitchen. Afterwards Ili had a chat to him and said that you must not bite anyone and that of a grown up bit another grown up they'd get in lots of trouble and be told off by police and go to jail. He hid under table and cried :( I know it was probably OTT but I really wanted to nip it in the bid (no pun intended). This is first experience of child biting and wondered WWYD? Oh and he's not allowed on phone today at all.
