I was just wondering what else I can do to stop my almost 3 year old from biting? He stopped for a little while and has started again. I've trying telling him that it's not nice, putting him in his room and nothing is working. He mainly only does it when he is frustrated say if a kid takes a toy off him he will bite them or if they are being mean to him. Thankfully he hasn't done it to 8 month DS3 but will do it to DS1 who is 4 and 1/2 years old almost and DS1 will come to me and tell me and not do anything to DS2 before coming to tell me. Normally DS1 has done something to upset DS2 and that's the way he lets DS1 know. I really don't know what else to do with him.
Do you have any tips at all that may help?
