I would sit down with your daughter and have a talk with her and tell her how you feel. (be carefull how you do it) I have a 7 year old and she knows that I don't like boys. This one boy came over asking if she could play (she was playing with her girl friend in our yard) I told him that she cannot play, in a stern voice. (Homey don't play that!) There is a kid in my daughters class that has exposed himself on the bus. His dad encourages him to ask girls to be their girlfriend, among other stuff. I had a lengthy discussion with the teacher and principal. I think the teacher saw the concern in my eye. I don't know how I'm going to handle it. I try not to think about it, because it upsets me to even think about it.
