Size 1 fits 6-20lbs (NB/SM). Size 2 fits 15-40+ lbs (M-XL)
Our 2-size adjustable system is easy and economical. You don't have to buy multiple sizes, and you don't have to contend with the poor fit of a one-size.
Designed by a Canadian mom and tested on her own babe, these covers are smart, user-friendly, and they WORK. Use them with lay-in inserts (reusable or disposable), prefolds, or for over fitted diapers. We recommend using our Size 1 Inserts for a perfect fit with your Size 1 cover and our Size 2 Inserts for a perfect fit with your Size 2 cover.
