How do I deal with a 9 year old who fights me EVERY morning to go to school?

I'm concerned that you constantly brought up the fact that she isn't your biological daughter.What does that matter?Could she be picking up on the fact that you hold this against her?I'm a firm believer in just picking the child up and taking them to school.Tell her she is going even if she has to go in her pajamas.I'll bet she'll get going pretty quick,girls don't want to be seen if they're not done up pretty for school.
