I read all the other responses and am glad that they actually worked for them, but I am a grandmother now and the whole swaddling things sounds like this is taking these children longer to adjust to sleeping on their own. That was something that was never recommended back when my children were young. When my son was around the same age he slept the whole night up until he hit the 4- 4 1/2 y/o and then did the same thing as far as waking up several times a night and wanting to be held and when he would go back to sleep I would put him in his crib and leave the room. Then an hour or two later he would wake up again. I took him to the doctor's thinking there was something wrong with him. According to the doctor, after a checkup, my son was waking up to get the attention. The more he would cry I would get up check his diaper and cuddle him and he would go to sleep. He advised me the only way to stop that is to allow him to cry, even if he cried all night. He told me that if he would cry, to get up and check on him to make sure he was not in any harm but not to let him see you. Then let him cry. He told me that it may take a week or so until he realized that you were not coming in to cuddle him at night. I was really upset about that but knew that it was the only thing that I could do. When he would cry I would get up and sneak into his room and look in on him to make sure that he was ok. He never saw me. The first two nights he cried for hours. But then each night the crying didn't last as long. Then in about a week, it was restful sleep all night. It was really hard to do but I knew that it had to be done. You have to be patient. But it worked for me.
Good luck honey. My son is now 31 y/o, married and a daughter with another child on the way. It's worth the sleepless nights!!!!
Let me know if it works for you. Your daughter will not hate you for it!!! And you will get your much needed sleep.
