Depends on the day and how she has slept during the day. e.g. tonight she was in bed and asleep by 6.30 because she wouldn't have an afternoon sleep so was knackered by then!
Normally when our day routine has gone to plan, I try and put her to bed between 7 & 7.30pm. However sometimes she doesn't want to go to sleep then (like last night!) and it may be 8 or 8.30 before she is finally asleep.
mine can skip any nap and be in bed by 6:30, 7, 7:30, 8 or later depending on her mood
