the oldest, the boy is 10. he is, the 6 yr old niece, she's babied and protected by mommy so she thinks she gets away with anything.... and sadly does. she'll hit, bite, kick, steal, etc. When she gets put in timeout, she screams and screams, we make her sit there until she stops. But when she goes home to mommy, we get chewed out for "being too mean to her". The boy on the other hand, no trouble at all and if he doesn do something and gets in trouble, he takes his punishment and moves on.
