Our day is varied depending on the time she wakes up. I try and aim for a 11.5 - 12 hr day so bedtime is brought forward. Even without her nap it takes her a long time to fall asleep and the same if she goes to bed later. Quite often she isn't happy about going to bed before her sister and will purposefully stay awake until she can hear her older sister has been tucked in bed around 7.30pm. On those days she can easily do 13 - 14hr days. She's refuses naps now and can manage to stay awake during car journeys unless exceptionally tired. The days she does have a power nap then she goes to bed too late, singing or playing in bed till 8.30pm ish if not later so not to keen on re-introducing naps. Hence thought maybe wake to sleep would be worth a try?
