Bethanie used to be in bed at 8, few reasons why..she used to have a nap after lunch so wouldn't be tired before 8. She was getting up too late though, more like 8:30-9am and it was making the day late/lazy.
We've just changed her routine, and it's much better. She gets up about 7/7:30am, goes for a nap about 12/12:30pm and goes to bed in the evening around 7pm. Bethanie is starting to wake earlier with the early sun as well though, maybe you could try black out blinds?
