I agree with jacmeldav, this worked with Madison as she was a bugger to get to sleep, and we only had to do this for about a week, and now she is a great sleeper.
With Charlotte she is great during the day will put her slef to sleep and will sleep twice a day for 1/12- 2 hours. She was in our room up till wednesday were we moved her into her own room, as she was up all the time over night for feeds, cuddles etc....., and the first night I had to rock her to sleep ( during the nights i have trouble settling her, so we rock to sleep) and she slept from 9:30pm to 3am then from 3am till 6am and then from 6am to 8:30, she did this for 2 nights and now she sleeps through the night from around 9pm till about 8am.
