Try some soft, made-for-babies, meditation music to comfort her into a restful relaxed sleep. Or there is also the music that offers nature sounds, like rain, frogs, crickets, etc. My little ones enjoyed the rain and thunderstorms cassette at bedtime. Occasionally they'd listen to the soft meditation music and relaxed instantly with this as well. I can say to this day, and they are all over 25 yrs old, they love the sound of the rain and thunderstorms!
I also sang to my babies when they were under the age of 1 to 1 1/2 yrs old. I sang and patted their tiny booties as they lay on their tummies with head turned to where they could see me standing there next to the crib. They feel of my hand on their tiny bodies, plus the sound of my voice, and just knowing I was there was comforting enough to put them to sleep. You have to have patience. If you go in a rush a little pat and then leave, they will always wake and scream again. Give them time to trust that you are protecting them. Feeling secure in your presence is not too much ask, especially when as a mom you remember they lived inside of you for 9 mths feeling completely protected and close to you.,
enjoy these moments when your little one wants to have you near. when 12 yrs of age hits, they won't want you within a 5 foot vicinity! lol...
