Argumentative 10 year old- May daughter is pushing back on everything. When told to do something (anything) she grumbles, sighs, complains, etc. My husband and I have been working on "yes mom, yes, Dad" for years, without success. Recently she goes to bed 15 minutes earlier for every time she back talks. If we were consistent, she would be in bed at noon! Any help to stop the back talk would be appreciated.
