Within the past year, the folks at Bummis introduced a 'preemie' sized prefold, intended to fit babies from 4-9 lbs. The name of this new size has proven to be a bit of a misnomer, most parents tend to overlook the preemie diapers because most babies are carried to term, parents generally don't plan for the possibility of a preemie baby. Nevertheless, we still encourage parents to consider stocking up on preemie prefolds, even though they may not get used for a long time, they offer considerable bang for the buck. There is a bit of overlap between the preemie prefold and infant prefolds, which fit from 7-15 lbs, but if you have a baby who weighs less than 8 lbs, the smaller fit of a preemie prefold will be considerably less bulky on your little one than an infant prefold.
In terms of what kind of cover to use with a preemie prefold, we suggest parents consider the size one Thirsties duo wraps which fit from 6-18 lbs (you can continue to use them with the infant prefolds when you size up), or the newborn Bummis super lite covers, which fit from 6-10 lbs, and feature an umbilical scoop to prevent the top of the cover from rubbing against your newborn's cord stump (which is as attractive as it sounds). We recommend that parents have 2-3 dozen diapers on hand to reduce the workload involved in washing diapers for those first few weeks. Newborn babies poop a lot (a lot!!), the more diapers you have on hand, the less frequently you will have to wash them. 2-3 dozen diapers (and 4-6 covers) would see you washing diapers once every 2-3 days for the first 6-8 weeks, which is totally manageable.
The upfront cost for 2 dozen preemie diapers and 4 newborn Bummis super lite covers would be $73.96. You can expect to change at least 12 diapers/day for the first 4 weeks of your baby's life. A single-use diaper costs approximately .25 cents, you would spend roughly $84.00 on
