We are relatively new to this type of cloth diapering so we are not experts. The one-size diapers are so fluffy soft it's hard to believe they are cotton. We love that. That said, these diapers are not ideal for a baby under 15 pounds. Yes, they can be folded down to accommodate a smaller baby but they get pretty bulky and we were not able to fit them under a Babee Greens medium wool diaper cover without diaper poking out the leg holes or top. We ended up using the diaper inserts with the doublers but that does not hold as much so changings need to be more frequent. We will try the whole diapers again when our baby is a little bigger.
