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.

If u prefer lo to sleep at 9pm, you need about 1 hour to let them wind down. Start milk at say 8pm, change, brush teeth and story time. By then they will take a while to totally fall asleep.
