You might have to do the tough love rule. I did it with my little guy and the child I take care of. Adventually she will lay her self down and go to sleep. You have to let her do it her self or it will become oh mommy will rock me to sleep and 2:00 am and she is up to be rocked to sleep! I've been there done that thing. Things to do while she is crying, listen to head phones (every 5 min take off and see if she is still fussing), Set a time limit that you think she will not cry that long for like 20 min, Make sure you stick to it or she will learn to cry that long and you will come in and rock her to sleep lay her back down say mommy loves you night night, then ndo it again adventually she will fall asleep. Then when she wakes up go right in and wisk her up and hug and kiss her all you want. I had to do that my son who is now 2. Boy did he know how to work me over.
