I read the book Healthy Sleep Habits Happy Child and used that for reference with my kids... I would recommend putting her down within 2 hours of when she wakes up (even if she doesn't seem sleepy) and see how she does with that. Often times if they get past their point of tired, overtired kicks in, but it can look like full of energy. That's how my kids are for sure. Then put her down for her afternoon nap as well.. Even if she doesn't always sleep, if you establish the routine and the schedule, she will fall into it, I'm sure. My kids did the very same thing you are describing (which is why I got the book! smile). I don't know all of the history here, but I noticed that my kids are very restless when they are cutting teeth and don't sleep or seem to be ABLE to take naps very well during that time, and then after a few days they are back to normal again. Even with that though, I put them down and let them look at books or "play" quietly in their beds. I have a 3 year old and a 1 year old. Anyway, I got that book from my library, and it was very helpful, just to know in general how much sleep they need at what ages, and how to work with their "internal clock" if you will. You might not have time to read the whole thing from start to finish, but the good part is that you can pick the chapter where her age falls and go with that until you have time to read through it more thoroughly. Sorry this is so long... just wanted to respond with details since I know what you are going through, having been through it (and worse!) as well.
