Mackenzie was a biter, still is sometimes. It is a frustration thing for her if she isn't getting her own way. She bites me now instead of other kids so I guess that is a good thing - if I can look at it that way! When we get bitten (or hit) she is sent to her corner. We just have to tell her and off she goes. Once she has calmed down we go over to her and ask her if she is sorry and give her a kiss. In saying this we only have Mackenzie and we aren't trying to juggle a feed in there! We have found this has worked the best for her. Sometimes if she raises her hand to hit I tell her if she hits me she will be going to the corner and you would be suprised to see her stop mid swing. No answers for you but this has worked for us. Good luck
