I noticed that my 9mth old baby has been coming home with occasional bruises from infantcare. I checked with the teacher and she got very defensive and said that she;s not sure how he got it. What do you think I should do?

If the person in charge of my child is unaware of my child's well-being, I will take appropriate action immediately and not leave room for ambiguity. It is unacceptable for him or her to be oblivious to how my child could possibly be bruised. At the very least, they should have information on possible reasons and be helpful instead of defensive. If it were me, I'd take my child elsewhere and make sure the school is aware of the situation so it doesn't happen again to any child.
