If you go directly to an hour plus keepin gher awake it will not help.
Does she sleep through the night? Before she stopped bottles was she waking early for a 'drink'?
It could be a few things, one being she may be thirsty. If you are giving her a sippy at 7, you could try giving her a pseudo dream feed, like water in a sippy, or even milk in her sippy at 5:30. This is what we do with our 13 mo old, and she sleeps until 8, or 8:30. For us it is a thirst thing. Our son was the same way (but just a bad overall sleeper).
You could try that, or you could try to gradually move her bedtime up, I would not suggest geting her to bed after 8, as then that leads to toddlers who get to bed at 10, or whatnot. And when you have a toddler running around the last thing you want is a toddler runing aruond at 20 while you are trying to relax
Hope this helps a bit.
