I heard about this in 2001 and bought one for use with my first child. Now we are parents of 2 kids, and we keep this sheet on the crib at all times. I keep the crib made with a waterproof mattress pad and a sheet, and put the ulitmate sheet on over the decorative sheet. It has saved loads of time and laundry, especially when we have poop accidents in the middle of the night. Now I change the baby and my husband unsnaps the ultimate crib sheet and our son is back to sleep in no time. Mine hasn't shrunk in the wash, but I wash it on cold and don't dry it in the dryer. I use oxyclean powder to get it white, and rinse twice. I think it's great and have suggested that all my mommy- friends get one! This makes a great baby shower gift.
