We have a six year old that misbehaves at bedtime. 'Defiant' is the best way to summarize her behavior - she turns on a dime at bedtime, actively disobeying what we tell her to do, and being mean to all in our family. Her history is that she often tries to get attention with misbehavior. We've taken away a weekly play group/extra curricular activities and we're running out of things to take away. She has had to sit on her bed many days after she's exhibited the behavior. What else can we do?
