my daughter the bully

Our neighbor brought her little girl Avery over the other day- she is just 2 weeks younger than Sloane. So far Sloane hasn't really taken to her and will usually just stay far away. When she came over the other day though, the second Avery grabbed one of Sloanes toys, Sloane ran over there and started screeching 'mom!' I guess she was telling on Avery! LOL! She did this for about 30 minutes, every time Avery would pick up a new toy. Then they were quite behind the couch, and when I looked Sloane was following her around and pushing her!!! Avery didn't even cry about it or fight back, she just took it! Poor girl. Finally after Sloane got in trouble she started being a bit nicer, but not much. Who knew, my cute little girl is a bully!
