I have some really small prefolds that I thought were newborn sized. I can't use the snappi to attach them to DS anymore. I asked my mom to get me some larger prefolds. When she went to the diaper store and told them the baby was 12 lbs. they gave her the same small prefolds and said anything larger would be too big. I'm realizing that if I just lay them in the cover folded in thirds they are the perfect size but I'm worried about leaking/blowouts if I don't use PFs with a snappi. What are your thoughts? Do you use snappis or not?
