Mother-Ease One Size Diapers are a basic fitted diaper. I am a cloth diapering mama of three girls, and have cloth diapered for several years now, so here is my two cents. ;) I found the Mother-Ease One SIze diapers to be way too big for a newborn or tiny baby. They are just too wide to fit on a little one. They worked well on my girls when they were in a medium sized diaper. At that point however, I just found them to not be quite absorbent enough. Mother-Ease does sell a doubler that you can add to this diaper. I did find it necessary to add that doubler every time. I really liked this diaper for using under cute wool pants. The diaper wears well over time and seemed to be well made. I appreciate that this diaper is going to last for some time. I just didn't end up choosing this diaper much. In the beginning it was too big. Another issue is that it does not have elastic around the legs, so that made is hard to contain that newborn breastfed baby poop that likes to leak everywhere. Around the medium stage it was ok, but then like I said later on we needed more absorbency.
