DD is 23 months old, but has had the same sleep routine since around 15 months.
She has an afternoon nap between 1 and 3pm. Sometimes she will sleep till 3.30 or even 4. I don't like her sleeping later than 4 as it means she is not really tired at bedtime and will be awake half the night!
Bedtime is 7pm, except for Thursday's - when her Pop comes over for dinner - then it is 8. Usually she is asleep within half an hour of putting her down. She is awake between 7 and 8am.
