A friend and his wife got divorced about a year ago. They have an 11-year-old daughter, M. M lives with her mom, and visits her dad about once a week. She seems fine when she`s with her dad, but recently has been acting up at home. The problem seems to be that her time with Dad is all fun stuff, while Mom gets to handle all of the discipline and not-so-fun stuff like making her do her homework. M seems to resent her mom, and Mom is getting really frustrated. How should the parents deal with this?
