My little girl has had to be swaddled tight to sleep practically since day one. I know she will be rolling over before we know it, so I'm wanting to start transitioning her out of needing it now and it's not going very well. I've started trying to just lay her down without it when she naps and she just lays there and throws her arms all over and wakes herself up. She just will not sleep unless her arms are tight up against her body. Any suggestions? She's sleeping through the night and I don't want it to be a struggle when she starts rolling and we can't swaddle her anymore.
