V.L.
I would try putting her to bed a lot earlier--6 or 7pm--and see if that helps. When we started putting my son to bed at 6:30pm (which does seem really early, but trust me!), he started sleeping much better immediately. Around 5:30ish, start looking for her tired signals (rubbing eyes, yawning) and nurse/give her a bottle, then put her in her crib. She might just be overtired. Good luck.
