Daycare seems to think I am a bad mom??

My 2 yr old son has been in a daycare centre since Sept, he seems to enjoy it there and I have no real problems worrying about his care there. However, the supervisor there is extremely rude, I don't like her whatsoever, she has a major attitude and I just don't like the things she says or her tone with the children. I have been ignoring this as she is not my son's teacher, his teacher is very warm and friendly.his supervisor has been questioning me about every knick and bruise he gets at home and will note it all down in her "book" right in front of me! She has made me feel so bad that I feel sick when I am dropping or picking up my son. She really seems to think I am abusive or neglectful. I could be paranoid, I don't know but I really can't take it anymore and I am about to pull him out of there. I just don't want to take drastic measures and harm my child's relationships or stability he has there.I am confused! If this *@# thinks I am seriously a bad mom then I don't want him ther
