About Diapers at BabyOneStop
Diapers are the one baby essential you will buy again and again, so it helps to know what you are choosing. Sizes are based on your baby's weight rather than age: newborn diapers usually fit up to about 10 lb, size 1 to about 14 lb, and each size up from there covers a wider weight range. If you see leaks or red marks around the legs, it is often a sign to move up a size.
This collection includes disposable tape-style diapers, pull-on training styles for active toddlers, overnight diapers with extra absorbency, and swim diapers for pool days. Many families keep one box of the current size and one of the next size on hand, since babies grow out of newborn and size 1 quickly.
Every US order ships free, and you can pair diapers with baby wipes, diaper rash creams and changing mats from the same cart.
Frequently asked questions
What diaper size should I buy for a newborn?
Most newborns start in Newborn size (up to about 10 lb) and move to Size 1 within two to four weeks. Buy one box of each to begin, then reorder as your baby grows; every US order ships free.
How many diapers does a baby use per day?
Newborns use 10 to 12 a day, 3- to 6-month-olds about 8, and toddlers 5 to 7. Our diaper size guide lists counts by size.
Do you sell overnight and swim diapers?
Yes. Overnight diapers have extra absorbency for 12-hour stretches, and swim diapers hold solids for pool days. Both are in this collection.
