Dear S.,
She will continue to wake up as long as you rock her. If nothing is wrong, and if she is dry, then let her cry. Talk softly to her as you examine her, and continue telling her that it is sleeping time for you and for Mommy too. 'I am not going to rock you now. I love you - here is your (favorite toy) and I am going back to my bed. Night night.'
Then you disappear - let her cry and tell anyonthat it is being disturbed that you are trying a new way to get her to understand that it is night time, and to stay in bed and sleep. Unless something is bothering her physically, then feel at peace as much as you can. The way things are going now the problem will probably not resolve itself. So you can try this way for now. Give it a good try - a week or so - anyway. I know that this is not what you want to do, but it is o.k. and will work. It makes the baby - who already adores you - trust you even more. I know that sounds crazy, but it isn't. Babies are smarter than we realize.
One thing about babies is that they need to learn to comfort themselves. Just like we do when we lay down to sleep. Get our pillow just right, and the covers just so and in our favorite sleeping position. They have to learn to lay down and wait for sleep too.
Good Luck, C. N.
