When she is involved in activities around the house, does she have difficulty staying focused and calm? Has her teacher ever told you that she has trouble staying in her seat in the classroom? If this behavior just happens at home and during mealtimes, it's probably for attention or she's just testing the limits.
Decide what kind of consequence will be most effective to change her behavior. Some people have suggested taking away her meal. If she enjoys an activity or watching a movie, video or playing on an electronic device after meals, think about taking that privilege away.
