Pros: An economical choice as one-size diapers grow with your baby and ensure you do not need to buy more diapers as baby grows from an infant to a toddler to potty training
Cons: thanks to daily wear and tear over two or three years - one-size diapers may not last well through multiple children, most one-size diapers start to fit around 9 or 10lbs - thus necessitating a newborn diaper solution (enter newborn diaper rental!), one-size diapers are bulkier on small babies
