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.

My 4 years old gal used to slp 11pm, after watching the 1030pm cartoon. I slowly move forward the timing by 10-15mins, then when she's ok, I move forward to another 10-15mins. So now she sleep before 1030pm and I'm ok with that.
