I discovered these layers when I had my second child and I also use for my youngest. What I like with these layers is that they are very absorbent and no leaks when using the right size. I also like the fact that no ball super absorber (SAP) will be stuck to the baby's skin. Note that my children have never been allergic or other reactions with these layers (or with their cloth diapers) unlike layers Pa per * * with which they have had almost burned buttocks.
