Quick answer
Start with Size NB diapers if your baby is around 6–9 lb (3–4 kg) and showing no signs of redness or pressure marks. Fold the waistband below the umbilical cord stump and move up a size when you see regular red marks or leaks.
Why Size NB is not a one-size-fits-all stage
Newborn diapers are cut for the first few weeks, but babies come in different shapes. A 7 lb baby with slender legs may stay in Size NB longer than an 8 lb baby with chunky thighs. The weight range on the pack is a starting point, not a strict rule.
Honest Clean Conscious Diapers in Size NB are designed for delicate skin and feature a soft, absorbent core. The fit depends on how you fasten the tabs and position the waistband, especially in the first days.
The umbilical cord stump: a fit problem, not a diaper problem
Many newborn diapers have a notch or a fold-down waistband to keep fabric away from the healing stump. If yours doesn't, simply fold the front waistband outward before fastening. This keeps the diaper below the stump and lets air reach the area.
Avoid pulling the diaper up too high or fastening it tightly across the middle. A loose, low fit for the first week or two is normal and safer for the stump.
When to move up: signs that Size NB is too small
Weight is only one clue. The more reliable signs are physical: red marks around the thighs or waist that don't fade within 30 minutes of removing the diaper, leaks that happen consistently (not just overnight), and tabs that no longer reach the landing zone without pulling.
If you see any of these, try the next size up even if your baby is still within the weight range. A slightly larger diaper with a snugger tab placement is better than a too-small one that leaves marks.
Newborn diaper fit FAQ
How do I know if Size NB is too big?
You'll see gaps at the legs or waist that leak within an hour of a fresh change, or the diaper slides down. Try fastening the tabs tighter or folding the waistband; if gaps persist, your baby may need a smaller size or a different brand's cut. Check for gaps at the legs before assuming the diaper is defective.
Can I use Size NB for overnight?
Yes, but change your baby as soon as they wake or if they fuss. Newborns poop frequently, and staying in a wet or soiled diaper too long can irritate skin. There's no need for a special overnight diaper at this stage. Prioritize frequent changes over long stretch absorbency in the first weeks.
What if the umbilical cord stump is still attached after two weeks?
Keep folding the waistband down and continue to avoid covering the stump. If it hasn't fallen off by three weeks or looks red, swollen, or smells bad, call your pediatrician. Diaper fit can help, but it's not a treatment. Persistent stump issues warrant a medical check, not just a diaper change.
How many Size NB diapers should I have on hand?
Newborns use 8–12 diapers a day, so a pack of 30–40 lasts about three to four days. Don't stock up on multiple large boxes; babies often outgrow Size NB within four to six weeks. Buy small packs first and scale up once you know your baby's growth pattern.
Does the Above It All print mean anything for fit?
No. The print is purely decorative. Size NB, Above It All uses the same cut and absorbency as other prints in the same size. Choose the print you like; fit is identical. Print choice is cosmetic; focus on size and fastening for fit.
