How to tell if your baby is getting enough milk (diapers, weight, feeds)
Published 1 October 2026 · Dao Van Thuong · 4 min read
You usually cannot see how much milk a breastfed baby drinks, so care teams judge it from what comes out and how the baby grows: the number of wet and dirty diapers each day, regular weight checks, and a baby who feeds often and seems content after feeds. Ask your midwife or doctor what diaper counts to expect day by day, because the numbers change quickly over the first week.
This guide explains each sign, how to count them on paper, and when not to wait.
This guide is general information, not medical advice. Follow what your doctor, midwife or health visitor told you, and call emergency services in an emergency.
Why is it hard to know how much a baby drinks?
With a bottle you can read the millilitres. At the breast you cannot, and the length of a feed says little: one baby drinks efficiently in a short feed, another needs longer. That is why the questions you are asked at checkups are about diapers, weight and feeding frequency, not minutes.
The World Health Organization (WHO) and the AAP both recommend feeding on demand — responsive feeding — rather than on a fixed clock. That makes a simple log more useful than a schedule: it shows what actually happened.
How many wet and dirty diapers should I expect?
Diapers are the sign you can count at home. In the first days the number of wet diapers usually rises day by day as milk comes in, and the stools change colour and texture. After the first week a settled pattern takes over.
Exact counts vary between guidelines and by how your baby is fed, so ask your midwife, health visitor or doctor for the numbers they want you to watch, and write them at the top of your log sheet. What matters is the count across a full day, and how it changes from one day to the next.
Disposable diapers can make wet ones hard to judge. Feel the weight of a dry diaper and compare, or tuck a piece of tissue inside if you are unsure.
Why does weight matter more than any single feed?
Most newborns lose some weight in the first days and then regain it; your care team will check when your baby is back to birth weight and how they gain after that. Weight is measured at the clinic on calibrated scales, so the trend across several visits is what tells the story, not one number.
Write each measurement down with the date, the place and, if possible, whether the baby was weighed naked. Home scales and clinic scales can disagree, so compare like with like.
What feeding signs are reassuring?
- The baby feeds often across day and night, and wakes for feeds.
- You can hear or see swallowing during breastfeeds.
- The baby comes off the breast or bottle relaxed, with open hands, and is alert and active at times when awake.
- Breasts feel softer after a feed than before, if you are breastfeeding.
None of these on its own proves enough milk, and none of them missing on one feed proves a problem. Together with diapers and weight, they make the picture.
How do I count all this on paper?
- 1Draw a sheet with one row per event and four columns: time, feed (side or amount), wet, dirty.
- 2Put a tick in the wet or dirty column for every diaper. A change that is both gets two ticks.
- 3At a fixed time each day — say 6 AM — draw a line and count the ticks for the past 24 hours.
- 4Write the daily totals in a small table at the bottom, next to the numbers your care team gave you.
- 5Bring the sheet to every weight check.
When should I call for help?
Call your baby's doctor or midwife promptly if diapers drop clearly below what you were told to expect, if the urine is dark or there are orange-red crystals after the first days, if your baby is very sleepy and hard to wake for feeds, has a dry mouth, yellowing skin or eyes that is getting worse, or fewer stools than expected, or if feeding hurts or simply is not going well. A lactation consultant can help with latch and supply. In an emergency, call emergency services.
Where Baton helps
Baton logs a diaper as wet, dirty or both in one tap, from the app or straight from a widget. Breastfeeds are timed per side, and bottles record the amount and whether it was breast milk, formula or mixed.
The Today screen shows the day's totals, and the free 7-day chart shows feeds and bottle millilitres per day. Weight, length and head circumference go into the growth log. With Baton Plus you can export a PDF report for your pediatrician; CSV export is free.
Both parents log to the same record through their own iCloud, so a diaper changed at 4 AM counts even if you slept through it.
