This works!
[This review was collected as part of a promotion.] My daughter is in potty training, and she only really struggles at night. We put this mattress guard on (which was not hard to do), and so far it has worked like a charm. At first it had a slight crinkle sound, but nothing too bad. After washing it once, it softened up and made even less noise. Now, I can't even tell it's on the mattress. My daughter has had 3 accidents while using this product, and the pee never reached the mattress. All around win.
