I am a cloth diapering mom and before my son was born i was making many cloth diapers using different patterns on the nappy network website and diaper covers from Katrina's Soaker Pattern.
These are newborn size, i found them to be more difficult to make than the other sizesbecause they are so small. i ended up making five newborn and never got to use one of them because my son ended up being born at 9lbs 9oz.
This is the size small. i made 6 of this size and i think he fit into them for just a few weeks.
For those of you who don't cloth diaper i would still recommend making some of these soakers to go over disposables. My little one has peed and pooped out of many of his diapers and after staining a couple outfits i started using the covers to help prevent leakage. They work like a charm.
