How am someone be so kind, loving and respectful at school, but so terrible and violent at home?

One of our students is the sweetest little girl. She acts polite, uses her manners, raises her hand, encourages her friends, isn’t boastful about winning and is a good sport. I know she’ll give us an attitude or a death stare when we redirect her but she doesn’t talk back much. After a meeting with her mom, the teacher we worked with said she is a terror at home. AWFUL AT HOME According to her mom, she slaps her, kicks her, curse at her, throws a fit when she has to do chores, she screams when redirected and punched her babysitter and her babysitter quit. She slaps her older brother and punched her last provider in the tummy and the provider quit. The once has to call the police on this little girl, TWICE. She ran away from home so many times. They went through several babysitters and care providers. I wasn’t shocked because kids so act differently but DAMN, I didn’t know she was this bad! She is so polite and a peer model. One of the other assistant teacher was shocked and disappointed. She said, “I don’t think I can look at our student the same way anymore.”

I told her, “Well that happens kids act differently at home because they’re comfortable releasing their feelings but what this little girl is doing is NOT okay! She should not be doing this and her mom needs to put her food down before she gets older and she’s a tall girl, skinny but tall. If you think every kid is an angel, then you’re delusional.”She’s 6 bit tall for her age. I told that little girl that her behavior is NOT okay and she better listen to mama or something big will happen at school (privileges will be taken away).
Our student never tries to elope from class or hits us. At her other schools she was terrible as well.
