Does anyone have experience with wool? My DD will be 4 mo old, and she is soaking through overnight. She's starting to sleep through the night, and I don't want to wake her for changes when we feed. We currently use Charlie Bananas, which are great during the day; but even double stuffing isn't helping. She leaks up the back, so I think it may be a flooding problem.
I don't want to try a bunch of different things, my research says that wool is best for the night.

So can anyone give me input?
Also, if I'm not supposed to cover the wool, what would she wear for pajamas, and a swaddle?
