My daughter is 6yrs old. We never went through the terrible twos but in the past year her emotions and attitude has taken a turn for the worst. the way she speaks to me is so disrespectful at times. She is always an angel for her dad but when it is just the two of us and she does not get her way she throws a FIT! I have been grounding her to her room lately. Also taken away electronics and fun activities. But it doesn't seem to last , she always does the same thing over again. Her behavior in school has been horrible as well. Always interrupting and causing a disturbance in the classroom..... Anyone have any suggestions for me to correct this behavior?
