Thanks everyone. I sent the mother an email this morning explaining my thoughts a bit better to her. I really hate talking on the phone so I just sent her an email saying that in no way did I want to terminate and that I am taking steps to prevent further incidents.
The boys bite for no reason. I was changing my sons diaper and one of the boys just grabbed his arm and went to bite it. They do it when frustrated sometimes, but mostly when they are playing. I think they get caught up in what they are doing and just bite (whether out of excitement or what, Im not sure).
Im going to talk to the mom of the bitten boy on Tusday when they come and explain my self then. Im not going to start beating myself up over this (which I pretty much did all Friday).
Thanks for letting me know I'm not alone. I just feel that this reflects on my ability to watch for the children. They are quick little buggers and most of the time I can stop them before they bite, but yesterday they got the best of me!
