Not the Victim?

So today is the day we had to sign the first incident report for Anthony at daycare where he was not the victim. We have reached that dreadful stage of biting. Last week we got a notice that he was sent to time out for hitting a friend. Then on Friday I learned he had also bitten someone - no report just a verbal warning I guess. Well, Monday - he was back to his tricks. This time, it left a mark on the poor victim (Logan - his best friend from daycare) so we had to sign the paper work. I hope this is not a sign of future misbehaving. I know biting is a phase they all go through, but I thought for sure my little angel would not be doing it. I was wrong!
