Okay, so my boyfriend and I have been together going on two years. We both have a daughter from previous marriages, my daughter will be three this month, and his will be five in January, we also share a son together who is 6 months. Well anyways, when I first met his daughter she was the sweetest thing, but that has all changed. Now she breaks things, for example she broke a lamp, and then broke my bracelet, and not literally five minutes after I had a talk about breaking other peoples things, she breaks my daughters wand. Then we have a sit and spin for the girls and it was my daughter's turn, well when I walked out of their room to go get the baby, I hear a loud thud, and go in the girl's room, and she pushed my daughter off the toy, and made her hit her head. Then, when we are in the car, she shakes her brothers car seat, even after I say stop continuously. Once I told her to stop then five minutes later she starts kicking it. She also is rough with him, and grabs him by the neck like he is a doll. I'm really at my witts end because she is constantly bullying my children. She hits my daughter, and takes her toys but doesn't share. She whines and cries and throws huge fits when she doesn't get her way. I'm getting to the point where I don't want her around, and talking to her, and grounding isn't working, and he even spanks her but nothing. If she's not the one getting all the attention or anything she is a brat. What do I do... I mean I have no clue... I've had continual talks with my boyfriend and he says he'll talk to her but we've done this, and I'm tired of my kids getting hit and bullied. EDIT: Her father and her do daddy daughter dates every week as well, so he spends one on one time with her, I understand the jealousy thing, but now its affecting the safety of my kids. We have her Friday-Monday, and no she has been bad before the baby, it just seems to keep getting worse and worse.
