The mother of the little girl I watch has told me she has been like this since the end of her summer vacation that she got to spend with her dad. I just started watching the children the begining of the school year. The first week I had her she was fine. Then after that she slowly started to withdrawl from me. I have told her mom that her little girl needs help and she does nothing. So to open her mothers eyes I have told her I could not watch her children anymore after this week. She seemed upset with me that I would do this to her. I think I am also going to try to get a hold of the girls father and let him know about the problems she is having. Because I don't think he knows there is anything wrong.
Your concern is justifed, because the behavior is rather unusual in a child this age. More than just the behavior in your home is the mother's information that the girl is like this at home as well. An important part of an evaluation will be to ascertain if this represents her baseline (i.e., general) level of functioning, even before her father left, or whether the behavior commenced after the departure of her father. If it is the former, it may indicate a general developmental problem. If the latter, it likely represents a depressive reaction to the loss of her father. In any case, the situation invites evaluation.
