So what did you all do at night when LO rolled over and woke up crying because s/he got stuck? We're using the Merlin suit at the moment but tried a few nights here and there with a sleep sack and every time LO gets stuck and wakes up. He's not great at tummy to back rolling yet but the other way he's fine. He'll roll onto his belly, inchworm to the end of the crib, then get on all 4s and get stuck. Then wakes us up because he's crying. Then the next night we put him right back into the Merlin! The Merlin has become a sleep crutch for us, and I want to try to get him out of it sooner than later.....
