I'm all about the Snuza, but the past few weeks H has been rolling and she has been doing it in the crib but I kept the Snuza on her bc she was still primarily on her back. Now she is officially tummy sleeping (finally turning her head instead of face-planting and giving me a heart attack when I look on the monitor- ha!)...Should I quit using the Snuza now? It seems like it would be kind of digging in her belly if she's sleeping on her stomach. She's 5 mos, btw....
