It didn't work for my son, he really didn't like to be swaddled, but my daughter loves it. She was getting very cholichy at night, but when we started using the SwaddleMe her fussy time went away, and she sleeps for long periods of time now. I don't go anywhere with out it and use it every night! I have even started using it for naps as well. It helps them not to startle themselves awake, and that is key. The fabric is soft and slightly stretchy and so easy to use, I could never really get a good swaddle with a blanket!
