How do you deal with a 3-4yo who refuses to sleep early? (9pm) and sleeps only closer to 11pm? I'm thinking of making my LO exercise until she KO. Heh.

Maybe you would like to accompany her to sleep first at 9pm. I have to accompany my girl into sleep before I can do my household chores at later night . They need sufficient sleep otherwise will be cranky on the next day!
