We are just coming out of a few biting months with DD. I don't know what started it and I don't know what is stopping it..

She might bite once a week now maybe and even then it isn't a proper bite it is just a graze now. She was mainly biting Ds3 and leaving huge bruises..

I refuse to bite back but I did tell the boys if she bit them again they had our permission to bite her. she never bit them after that. Well apart from a few grazes on DS3. I didn't really want the boys to bite back but I think DD got the message quick smart. She is smarter then she lets on lol

I am not sure if this sort of thing would work with your kids as there is just under a years difference in age and understanding
