Zen Sack?

Annika

Has anyone used the Zen Sack to help with a swaddle transiton?? My daughter just started rolling so that's goodbye to the swaddle and has been waking up every 2-3 hours when she used to sleep in stretches of about 6 hours at a time. I'm seriously hating it as she has been a good sleeper right from the get-go. Any success with the weighted sack?? Any tips/advice??
