My little one recently figured out how to roll from back to belly. When I lay her down she usually rolls to her side and sleeps on her side. Tonight she keeps rolling to her belly. Normally I'd have no issue with this as I know she can lift her head and roll but she starts screaming once on her belly. As soon as I roll her back to her back she stops but minutes later she rolls back to her belly and the whole cycle starts over again. Any suggestions on what to do? Anyone else deal with this?
