I am so sorry this is happening to your family and I wish you the best. I don't have a solution to tell you for how to handle the next 2 weeks... but I just wanted to point out for anyone looking for a new day care center that one thing I think is important is a director should NOT also be one of the teachers! If they are filling in for a VERY short period of time that's one thing, but if a director is also a full time teacher then the safety of the kids is not the #1 priority of the center. If teachers or parents have any issues, they should be able to rely on the director to do her job overseeing the program without having to take time away from supervising a group of students. Who answers the phone when it rings? Who gives tours of the center to parents who stop by? Who watches her class when a parent or teacher needs to speak with her?? Of course home day cares are different, but if a center is large enough to have several classrooms and a director, then the director should not also be one of the teachers. Just my 2 cents.
Also- as for the biting issue... some kids go through a biting stage and there is no 100% guarantee (unfortunately) that our children will not be bit by other toddlers. It's how the situation is handled that's important. Your center did NOT handle it in a way that makes you feel safe and it's a shame other parents in the center aren't aware because the biter will now bite other kids (although he may be already doing this!)
