The Sunbaby One Size Diapers are one of the most adjustable one size cloth diapers on the market! Adjust the diapers to fit babies 7-35 pounds and get a snug fit every time with the snap -adjusted in waist and leg.

Strong absorbent material with breathability keeps the skin dry and helps to prevent diaper rash. Our product absorbs urine fast and reduces the chances of developing bacteria from sleeping in a moist diaper.

Difference in size

The Differences Between Size 1 and Size 2

Even though Sunbaby diapers are a “one size fits all” diaper, we realize that every baby is different. Some babies are slim and some are chunky. Slim babies will fit nicely into our size 1 diapers, whereas chunkier babies will welcome the slightly larger size 2 diapers. And while you may not be able to tell that there is much of a difference, your baby surely will.

The Differences Between Microfiber, Bamboo & Combo Inserts

You might be asking yourself what is the “better” insert to use. Truthfully speaking, it’s really subjective and is based most on your preference. Microfiber is pretty absorbent and can often draw more wetness faster than bamboo. The drawback is that microfiber is more bulky and not as absorbent as bamboo… which can be less reliable for heavy wetters. However, we now have a 4 layer microfiber insert for heavy wetters or it can be used as a nighttime insert.

Bamboo inserts are ultra absorbent and are a bit thinner overall. Bamboo draws the wetness to spread more evenly throughout the insert, which makes it much more absorbent. The drawback is that bamboo doesn’t absorb as quickly as microfiber… and that can cause leakage for heavy wetters.

The combo blended inserts are a bestseller and seem to have a happy medium between both microfiber and bamboo. Bamboo is on the outside drawing the wetness more evenly into the microfiber below it and away from your baby. Combo inserts are 4 layers thick, with bamboo being on the outside and microfiber being on the inside. A true “win-win” for both baby and parent.

How do I use my SUNBABY One Size Cloth Diapers?

Put the insert in your diaper. Hold the insert in one hand and place inside the slot. Align the front edge of the insert with the top edge of the snap strip.

Using one hand to hold the front of the insert in place, stretch the diaper and smooth the insert flat as you pull your other hand out of the diaper.

We suggest changing as often as every 2-3 hours and adding more inserts to the pocket during nap and night time.

Adjust the diaper sizing by choosing the right snap setting on the front of the diaper. Your diaper arrives snapped down to the “large” setting; fully unsnap the front of the diaper. To use the “medium” setting, snap on the second row of snaps. To use the diaper on the “small” or “extra small” setting, snap on the bottom row of snaps.

Introducing Our Newly Designed 4.0 Version

The new Sunbaby version 4.0 one-size pocket diapers have been completely re-designed. Hip snaps have been added to assure a perfect fit around your baby’s thighs from skinny newborns to chunky toddlers. The 4.0s also have wider and more comfortable elastic than the previous versions. This new elastic is also super-stretchy for a better fit that won’t dig into your baby’s back or legs. The fabrics have also been upgraded to a new super-soft micro fleece inside and a thinner higher quality PUL (polyurethane laminate) outside shell.

Our discontinued Sunbaby 3.0 one-size pocket diapers had a narrower crotch and a slimmer overall fit. They had a thicker more durable outer fabric. Version 3.0 also had a smaller and narrower microfiber insert than the newer, more improved 4.0 version.
