How many wet and dirty diapers should a newborn have each day in the first week?

By Jack Wallner · Updated October 12, 2026

Newborn diaper count by day

This table follows the NHS Healthier Together guidance for breastfed babies. Each row is the minimum for a 24-hour period, so more is fine.

The AAP's HealthyChildren.org gives a slightly different framing for the same pattern. It lists 1 or 2 blackish, tarry stools a day on days 1 and 2, at least two stools turning greenish to yellow on days 3 and 4, and yellow, loose stools with small curds at least 3 to 4 times a day by 5 to 7 days old. It also lists 6 or more wet diapers a day, with nearly colorless or pale yellow urine, by 5 to 7 days old. The two sources agree on the direction: counts climb through the first week and settle at 6 or more wet diapers.

Why the numbers climb

Diapers are a practical way to see feeding going well without measuring anything. The AAP notes that when breast milk production increases, a baby will often have a stool with each feeding for the first month. That is why the dirty diaper count keeps rising after the first few days.

Details that trip parents up

Orange or rust-colored spots

On days 1 and 2 a diaper may contain rust-colored spots called urates, which are concentrated urine. The NHS guidance says they are not a problem at that age. If they continue beyond the first couple of days, it advises telling your midwife (in the US, your pediatrician or lactation consultant) because it can be a sign that a baby is not getting enough milk.

Disposable diapers are hard to judge

The NHS guidance says it can be hard to tell whether a disposable diaper is wet. Its tip is to pour two to four tablespoons of water into a clean diaper once, so you know what a wet one feels like and how heavy it gets. From day 5 the guidance says to expect heavy wet diapers.

Later in the first month

After 4 to 6 weeks, when breastfeeding is well established, some breastfed babies go a few days or more without a bowel movement, and the NHS guidance says this can be normal. The wet diaper count should stay at 6 or more a day.

Formula-fed babies

The ranges above are written for breastfed babies. If your baby is formula-fed or combination-fed, ask your pediatrician what to expect rather than assuming the same numbers.

When to call the pediatrician

Counts are a guide, not a diagnosis. The NHS Healthier Together guidance says to contact a doctor or nurse the same day if a baby has fewer wet diapers than before, is feeding much less often or for much shorter periods, is not gaining weight or is losing weight, or seems drowsy or irritable. Call your pediatrician if your baby's diaper count is below the table for their day, or if you are simply worried.

The same guidance lists signs that need urgent help: a baby who cannot be woken for feeds, is breathing too fast to feed, is pale, mottled and abnormally cold, has blue lips or has a seizure. In the United States, that means calling 911 or going to the nearest emergency department.

The AAP also advises scheduling the first checkup with the pediatrician or family physician no more than 48 hours after hospital discharge. The weight check at that visit helps show whether the baby is getting enough from feedings.

Baby Tracker: logging the count

Baby Tracker is a free baby tracker for iPhone and Apple Watch. One tap logs a wet or dirty diaper, a feed or sleep, and the first-week view shows your running count for the day next to the typical range for that day of life, so you do not need to keep a paper tally sheet at 3 a.m. It records what you log and shows the typical ranges. It does not tell you whether anything is wrong, and your pediatrician's advice comes first. Partners can share the log through iCloud, which helps when two people are counting the same baby. See the Baby Tracker app page.

How many wet diapers should a newborn have in 24 hours by the end of the first week?

The AAP's HealthyChildren.org lists 6 or more wet diapers a day, with nearly colorless or pale yellow urine, by 5 to 7 days old. The NHS guidance also gives 6 or more heavy wet diapers a day from day 6.

How many dirty diapers should a newborn have in the first week?

Are the numbers different for formula-fed babies?

What if my newborn has fewer diapers than the table?

Call your pediatrician. The NHS guidance says to contact a doctor or nurse the same day for fewer wet diapers than before, and to seek urgent help if a baby cannot be woken for feeds or has trouble breathing.
