- They are incredibly economical since they grow with your baby
- They are a great option for families who have more than 1 child in cloth diapers since children can "share" diapers
- They allow you to change settings on the diaper to accommodate change in baby's body shape as well as extra bulk for overnight diapers
- Most one-size diapers don't start fitting till 8-10 pounds (depending on baby's shape) so you will have to use a "newborn" diaper in the mean time, or some families choose to use disposable diapers till their little one fits into their one-size diapers.
- Since the diapers have to last through toddler hood, there will be some extra bulk on a smaller baby.
When you are first trying one-size diapers on your little one, keep a few things in mind.
- They're going to look HUGE! But remember your baby is going to grow SO fast and they don't move around much as a newborn anyhow.
- Check the common spots for leaks do to poor fit. Lift their legs up and make sure you don't see any gaps. Make sure wings are tucked in and there is no gapping around the front.
- Try a few different brands. Something that fits your baby at 3 weeks might fit completely different at 3 months. I generally do not suggest people build their entire stash out of the same brand if they haven't tried other brands yet.
- Use a sized insert! Many one-size diapers come with 2 inserts, one of them usually termed a "newborn" or "small" insert. Take advantage of these as they will reduce bulk. Another great option is a system like the Best Bottom Diaper with the sized inserts that keep the diaper fitting nice and trim!
The BumGenius 4.0 One-Size Pocket Diaper is stuffed with 2 newborn inserts. It adjusts with a snap up rise and the stretchy tabs allow for a really custom fit around the waist. These started fitting Emmett (who has very skinny chicken legs) right around 10 pounds. These are also available in a hook & loop closure.
The Fuzzi Bunz One-Size Pocket Diaper is stuffed with the "small" insert. It adjusts with elastic in the back and legs to get a great fit! I did find these to have a little more bulk to them when the legs are cinched very tight but they fit closer to 9 pounds.
This Best Bottom One-Size Diaper has a small hemp/organic cotton insert snapped in it. These adjust with a snap up rise and close with either snaps or hook & loop around the waist. The extra leg gussets hold even the messiest of messes. These started fitting Emmett at about 9 pounds.
This Blueberry Coverall has a small Imagine Smart Fit Prefold under it. These generously sized covers fit suprisingly well on a small baby. The extra leg gussets also contain messes well! And just a sidenote, this particular cover was originally purchased for my now 4 year old when he was 1 1/2! This is the third child to wear it! :)
This Imagine One Size Pocket Diaper is stuffed with a small Nicki's Microfiber insert. The inner fleece of this pocket is so incredibly soft and the PUL has a really nice stretch to it. This diaper started fitting Emmett when he was about 10 pounds.
