Review on Knlpruhk Waterproof Pack N Play/Mini Portable Crib Sheet Set 2 Pack: Ultra Soft, Cute Animal Design, 100% Jersey Cotton, for Baby Girl/Boy by Ben Karlen

Bought because my son used to burp in his backpack and play occasionally and was difficult to clean (not to mention stains). This is great because you can change them as needed. Wash them right away as you can't use a dryer and it takes a day to dry (quite dry in the evening if you wash in the morning, but best left overnight). Drying may take longer if your washing machine has a very good spin cycle or if you wash by hand. The fit on Pack n Play is pretty good. Make sure you line up the corners correctly, then fold the sides down so they lay flat with no extra material.
