How many diapers will you need?
Stool colour guide
| Black, sticky | Normal in the first 3 days (meconium). After that, call your doctor. |
| Green, yellow, mustard | Normal. Breastfed stools are loose and seedy. |
| Brown or tan | Normal, common in formula-fed babies and once solids start. |
| Red or blood | Call your doctor. Some foods can colour stool red, but do not assume. |
| White, gray, clay | Call your doctor right away. It can mean bile is not reaching the stool. |
Signs of dehydration
- Fewer wet diapers than expected, or dark yellow urine
- Dry mouth, no tears when crying, a sunken soft spot
- Unusual sleepiness or fussiness
Call your doctor the same day if you see these signs, especially in a young baby. Source: AAP, CDC and children's hospital guidance. This tracker is not medical advice.
How to use
- Enter your baby's date of birth and the type of milk.
- Choose the stool colour, then tap Wet, Dirty or Both at each change.
- Check the last 24 hours against the guide for your baby's age, and watch for stool colour alerts.
- Enter your pack size and price to see how many diapers you will need each month.

How Many Diapers Is Normal?
Diapers tell you more than you might think. A baby diaper tracker helps you see, at a glance, if your baby is feeding well and staying hydrated. Our free baby diaper tracker counts wet and dirty diapers, compares them with the guide for your baby’s age, and warns you about stool colours to report.
This guide explains what is normal, what is not, and when to call your doctor.
Why Diapers Show How Well Your Baby Is Feeding
In the first weeks, you cannot see how much milk your baby drinks. Diapers give you the answer. Wet diapers show that your baby is getting enough fluid. Dirty diapers show that milk is moving through the gut.
For this reason, doctors often ask: “How many wet and dirty diapers does your baby have?” A written log gives a clear answer. If you breastfeed, pair it with our Breastfeeding Tracker for a full picture.
How Many Wet Diapers Should a Baby Have?
The number rises in the first days, then levels off. Count the diapers over a full 24 hours.
| Day of life | Wet diapers (at least) |
|---|---|
| Day 1 | 1 |
| Day 2 | 2 |
| Day 3 | 3 |
| Day 4 | 4 |
| Day 5 and after | 6 |
The CDC lists fewer than 6 wet diapers and fewer than 3 stools by day 5 as a sign that your baby may not be getting enough milk. Talk to your doctor if this happens. After about 3 months, a baby may have slightly fewer wet diapers, around 5 to 6 a day.
Remember that day 1 is the day of birth. Our tracker counts the day for you from the date of birth.
What Is Normal Poop in a Breastfed Baby?
Stool changes a lot in the first week. Here is the usual pattern, based on CDC and AAP guidance:
- Days 1 and 2: black, sticky stool called meconium.
- Days 3 and 4: stool turns greenish, then yellow.
- Days 5 to 7: yellow, loose and seedy stool, at least 3 a day.
- First weeks: many breastfed babies stool after almost every feed.
- After about 6 weeks: stools often become less frequent.
A breastfed baby with a very loose, seedy yellow stool is usually healthy. Nothing about this means diarrhoea.
What About Formula-Fed Babies?
Formula-fed babies often have firmer, tan or brown stools. They may stool less often, sometimes once or twice a day, and some skip a day. Stools that are very hard, or that look like pebbles, are worth mentioning to your doctor.
The wet diaper guide above is the same for formula-fed babies. If you use formula, check that your baby is getting enough with the Baby Formula Quantity Calculator.
Baby Poop Colour Guide
Colour is one of the best clues. Most colours are normal. A few need attention.
| Colour | What it usually means | What to do |
|---|---|---|
| Black, sticky | Normal in the first 3 days (meconium) | After day 3, call your doctor |
| Green, yellow or mustard | Normal | Nothing needed |
| Brown or tan | Normal in formula-fed babies and once solids start | Nothing needed |
| Red or blood-streaked | May be blood in the stool | Call your doctor |
| White, gray or clay | Bile may not be reaching the stool | Call your doctor right away |
Some foods and medicines can change colour, but do not assume that is the cause. When in doubt, call.
Once your baby starts solids, stool will change in colour and thickness. Our Baby Solid Food Start Planner shows when to begin.
Signs of Dehydration
Fewer wet diapers than expected is the earliest sign. Watch for these too:
- Dark yellow urine
- A dry mouth
- No tears when crying
- A sunken soft spot on the head
- Unusual sleepiness or fussiness
Call your doctor the same day if you see these signs, especially in a young baby.
How Many Diapers Will You Need?
Babies use more diapers early on. Newborns often go through 8 to 12 a day in the first month. After about 3 months, this drops to around 6 to 8.
Here is a simple example. At 10 diapers a day, a baby uses about 300 a month. With a pack of 40, you need 7.5 packs, and one pack lasts 4 days. Our tracker works this out for you. It uses your own log once you have 3 full days of data, and a typical number for your baby’s age until then. Add your pack price to see the monthly cost, and compare it with your plan in the Baby Budget Calculator.
What the Diaper Tracker Does
- Logs wet, dirty or both with one tap, and records stool colour
- Compares the last 24 hours with the guide for your baby’s age
- Warns you about red, white or gray, or black stool after the first days
- Shows a 7-day chart of wet and dirty diapers
- Lets you download a CSV or print the log for your doctor’s visit
- Keeps your data in your own browser, so nobody else sees it
Because data stays on your device, it will not appear on another phone or computer. Use the CSV if you want to share it.
Tips for Accurate Tracking
- Log each diaper as soon as you change it. Memory is unreliable at 3 a.m.
- Use full 24-hour periods. The tracker tells you when a count is still incomplete.
- Note the colour when it looks unusual, and keep the diaper if your doctor may want to see it.
- Share the log at check-ups, along with your baby’s growth on the Baby Height and Weight Percentile Calculator.
When to Call Your Doctor
Call your doctor if:
- Your baby has fewer than 6 wet diapers by day 5, or fewer than 3 stools by day 5 while breastfeeding
- You see red, white, gray or clay-coloured stool, or black stool after the first days
- You notice signs of dehydration
- Your baby feeds poorly, seems yellow, or will not wake to feed
- You are worried for any reason
Keep vaccines and check-ups on track too. The Baby Vaccination Schedule Calculator lists due dates for 11 countries, plus the WHO standard schedule, and the Baby Age Calculator gives your baby’s exact age. If you pump or give milk by bottle, the Baby Feeding Reminder helps with timing.
