How many wet diapers should a newborn have a day? How to count them without guessing

NHS services describe a number that climbs in the first days as milk comes in. One NHS trust (Dorset Healthcare) says that from about day 5 or 6 a baby should have at least 6 heavy wet nappies in 24 hours. Another NHS service (NHS Grampian) gives 5 or more for the same days, and an NHS trust in Frimley gives a rule of thumb for the early days: roughly as many wet nappies as your baby is days old, up to about 6. The exact wording differs between services, so use the numbers your own midwife or health visitor gave you.

Heavy matters more than a quick glance. A wet diaper is one that feels clearly heavy with urine, not one with a few drops. Disposable diapers are hard to judge, and some NHS trusts suggest pouring a little water into a clean one so you learn how a wet one feels.

These sources describe what is expected, not a target to hit by changing how you feed. A day with 6 wet diapers and a day with 8 are both normal for many babies.

The same services also give figures for dirty diapers, and the colour and texture change over the first week from dark and sticky to yellow. Because it depends on how your baby is fed and how old they are, the useful habit is to record each one and ask your care team what to expect. Our guide on newborn poop colour covers what to note.

At 3 AM, nobody remembers whether that was the third or the fifth. Write each change down as it happens:

• The time.
• Wet, dirty or both. A diaper that is wet and dirty counts for each.
• Anything unusual, such as a very dark or very pale stool, or a diaper that was dry after a long gap.

At a fixed time each day, say 6 AM, count the wet diapers in the past 24 hours and note it next to the day's age in days. Written down, a count is easy to read out to a midwife, and a gap between wet diapers becomes visible instead of a feeling.

Tap Diaper on the Today screen, then wet, dirty or both. On the medium Home Screen widget there is a button for a wet diaper, and Siri or the Control Center control on iOS 18 can log one by voice or tap, so you do not need to unlock your phone with a baby on your arm. The medium widget also shows the most recent diaper, and Today's timeline strip includes diapers.

In Charts, the daily total shows wet and dirty counts separately, and a diapers-per-day chart shows the week as bars. The 7-day charts are free; 30- and 90-day trends are part of Baton Plus. A diaper logged as both counts once as wet and once as dirty. History lists every diaper with its time, and CSV export is free.

Baton counts what you enter. It does not tell you how many wet diapers your baby should have, and it does not say whether a count is too low.

Contact your midwife, health visitor or pediatrician if your baby has fewer wet diapers than they told you to expect, if a diaper stays dry for a long time, if the urine is dark, if your baby is unusually sleepy and hard to wake for feeds, or if feeding does not seem to be going well. Do not wait to finish the log first. Bring it with you: a few days of times is easier to discuss than memory. In an emergency, call your local emergency number. Our guide on whether your baby is getting enough milk explains the other signs care teams look at.
