I babysit a little girl in my home on a part time basis right now. I was watching her full time until recently when her mom's work slowed down. I have been caring for her since she was a baby and now she is in preschool. While she was coming to my home full time she was kind of bossy and mean to my now 1 year old but nothing to worrisome. Now that she is only coming a few days a week and is home with her Mom most days(she is an only child) she has become mean and really bossy to DD. Anytime DD tries to play with a toy B takes it away and yells "No A that's mine!". She also runs around screaming hysterically anytime she thinks DD is trying to get her toy even when DD is not even interested in the toy and is doing her own thing. Anytime I try to correct the behavior by saying "lets share" or trying to give B something in place of the toy she just snatched from DD B breaks out in this crazy dramatic tantrum screaming, crying, and just being crazy dramatic. I am seriously at a loss on what exactly to do. I totally understand some of this behavior is completely normal but I do feel it is a bit extreme at this point. She is being SO mean! I really like her mom and her family so I am really struggling with a nice way to tell her mom about the issues. What should I do? How should I bring it up without sounding like I am talking negatively about B?
