@boomerang,
Yes, boomer!
I've been down that road and I did it all - explain the repercussions, tried
to bribe her, entice her and threaten her. Bottom line always was that I forced Jane to sit down right that moment an do her homework. At first she was just staring at the page and did nothing and I told her that I don't care if she sits there until bedtime, she stays there until her homework is finished.
Usually, she had another five or 10 minutes of pouting but then she started
doing it and before you know it she was finished and quite happy.
Unfortunately, we still play these games....*sigh* In elementary school, Jane
came home and immediately did her homework, middle school was more of
a challenge and now in high school it's a real struggle. She's a good student,
but homework is not something Jane wants to do.
