I bought a couple of these sheet covers for the crib and they are wonderful since you don't have to change the entire bed if baby wets the sheet cover. My concern is the safety of these sheets since there are six snaps that attach to the crib bars. Does anyone know of any situations where babies have been known to unsnap these and cause a problem? My four month old is starting to get more mobile and I'm concerned about the safety of the sheets.
