C.,
You should start a ritual. Maybe after you feed her, give her a bath with some lavender in it. Maybe tell her a story even though she is sooo young it would be a bed time ritual you can continue untill she is 8 or so. It worked for my sons. I read it once in a parenting magazine. You could choose anything to do as long as its the same thing everynight that way she knows when she gets her bath and a story or a massage with smelly lotion she knows that its time to go night-night.
Here's another thing that worked, I gave my youngest son a pacifier only at night time so he looked forward to going to bed because he knew he was getting his ninnie.
Good luck,
C.
