I got this sheet as a present for my first child. I never used it as a crib sheet but as a mattress pad because it seemed inconvenient to change with all the snaps. A friend gave me a crib sheet that is safe and it is so easy to change called the QuickZip crib sheet. My baby can't pull it off the mattress! When I change it, I just zip off the removable sheet and zip on a clean one. No lifting the mattress or bumpers. This is my solution for my child.
