Ok, hive, I'd like your opinions. We're out of town at my MIL's so I don't have a sleepsack with us. DD has been sleeping in the Merlin but with her naps today she started rolling in it consistently. I know she can move in it fairly safely because she can army crawl all over the crib in it, BUT she can't roll from belly to back. The problem is that the room we are in is freezing! So what would you do?
