My son is a biter. He's a toddler, and he has a bad habit of biting the other children in his class. We have him at a Montessori pre-school, so instead of day care he has teachers and a principal, even though he's not yet two years old. It's a great experience for him, but every day or so we have to sign a form at the end of the day when we pick him up acknowledging the fact that he has bitten some other toddler.
The school is kind enough to keep things anonymous. They don't tell us who he bit, and presumably they don't tell the other parents which child bit theirs. Sometimes I pick him up and the form I have to sign says that another child bit him instead, and it's gotten to the point where that's a relief. At first my snarky attitude was that it's better to be the biter than the one getting bitten; now I just hope it wasn't my son doing the biting.
