I know there has already been a lot posted about biters recently, but since many of us struggle with this, I thought it would be safe to post again on this topic. I have had a biter in my daycare before who I have been able to teach mostly not to bite (he will still do it occassionally, but not hard...he is almost three). His parents were great about working on it at home too and backing me up, so I kept on working on it. Otherwise he is a completely non-agressive child. Now I have another one who is 18 months and he has been biting a lot recently...today he left huge red marks on another child's arm and this wasn't the first time. he has also been hitting, but he may have picked that up from another child who was doing it and has since stopped. The hitting I find easier to deal with, but the biting is really problematic. I can't be sending other children home with bite marks all the time! I give him instant time-outs for biting and talk to him in a serious "I mean business" voice. I also don't leave him alone with the other children, but it still happens when I am there and busy with someone else or turn my back for a second. He will go and try to grab a toy from another child and then get angry and bite when the other child resists. I have spoken to the mom about it and she says she is trying to nip it in the bud, but from what I have seen, she speaks to him so sweetly when he does something wrong, that I really don't think he is getting the message. Any advice on stopping biting? I don't want to have to terminate him as I like him and his family, but I also have to protect the other kids. How do you all deal with biters? Do you stick it out and work with it or do you terminate???
