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.

You can start a routine like bedtime stories time & lights off for the whole house at 8:30pm. Enjoy the 30mins cosy bedtime stories time with your kid & slowly they will relax at your preferred bedtime hour & sleep early
