The Complete Guide to Diapering: Sizes, Changing, Rash, and Cost
5 min read
Diapering comes down to four things: the right size, changing often enough, keeping the skin dry, and planning for the cost. Get those right and the rest takes care of itself. Here is all of it in one place.
How many diapers you will actually use
A newborn goes through 8 to 12 diapers a day, dropping to about 6 to 8 by the second half of the first year. Across that first year, most babies run close to 3,000 diapers. Knowing the number helps you buy ahead and avoid the 9pm store run.
What it costs
Plan for $80 to $100 or more per month, per child. Over a year that is more than a thousand dollars on a single item no federal program covers. If that math is tight for your family, our guide to diaper assistance lays out every path to help.
Getting the size right
Diaper size goes by weight, not age. Newborn fits up to about 10 pounds, Size 1 is 8 to 14, Size 2 is 12 to 18, Size 3 is 16 to 28, and up from there, per the Pampers size chart. When your baby falls between two sizes, size up. Move up when you see red marks, frequent leaks, tabs that no longer reach, or a diaper that rides low. Full detail is in what size diaper your child wears.
How often to change
Change a diaper as soon as it is wet or soiled, and for a newborn, about every 2 to 3 hours even when you are not sure. A soiled diaper left on too long is the number one cause of rash. Poop always gets changed right away, even overnight. More on reading the signs is in how to know when to change a diaper.
Preventing diaper rash
Keep the skin clean and dry. Clean gently with water or a fragrance-free, alcohol-free wipe, pat dry, and apply a thick layer of a zinc oxide or petroleum barrier cream at changes, as KidsHealth recommends. A few minutes of diaper-free air time helps, and a loose fit lets the skin breathe. If rashes keep coming back, our post on why your baby keeps getting diaper rashes covers the five usual causes.
When to call the pediatrician
Most diaper rash clears in two to three days with home care. Call your pediatrician if it does not improve, if it is bright red with raised bumps or blisters, or if it comes with other symptoms. Those can point to a yeast infection or something that needs treatment beyond a barrier cream.
Diapering through military life
Moves and deployments add a layer civilian parents do not face. Buy ahead for a PCS move so you are never stranded in a new town without your size, and know that a deployment can set potty training back for a while, which is normal. None of it means you are doing anything wrong. It means you are doing this on hard mode.
