At that age... Whenever

930-10pm

She was in school pre k by 730-800
Napped at school

Never bothered her one bit she only went to bed before 9 pm when kindergarten started. She's in bed by 830 most nights.

We tried earlier times because it seemed the norm. Never worked for us. Put her to bed early, she'd wake up in the middle of the night, not sleep solid, be cranky. It was horrible. So we stopped it. We never did CIO and although she slept with us in the beginning, by 3 she slept alone.
