I have always used these layers since the release of motherhood and I have never had a leak for the time (even when the nights Baby last 10 hours). Moreover, they are very thin, which seems to be well comfortable and scratch even stand after several repositioning. For now, it is the layer I prefer.
Moreover, I find this very interesting set of layers because the price of these layers in my supermarket is 42 cents each, even on large packs!
