I took a chance on these when my baby was leaking through his diaper overnight though we had overnight diapers and had even sized up as recommended. These are AMAZING. Great price, easy to use and they WORK! It works very similarly to a maxi pad with an adhesive back that can be positioned wherever you need it. It worked wonders the very first night and I was sold. No more wet baby, wet bedsheets, no more pee smell and no more fuss. I can't say enough good things about these.
