How many diapers should a baby have per day?
Counting diapers is one of the most practical ways to tell whether your baby is getting enough milk, especially in the first weeks when you cannot see how much a breastfed baby drinks. Here is what is typical, and when to ask for help.
Why diapers matter
What goes in must come out. A baby who is drinking enough milk will pass urine and stool regularly. Together with steady weight gain, alertness between feeds and contentment after feeding, diaper counts give a good picture of how feeding is going.
Typical numbers in the first week
Day 1: at least 1 wet and 1 dirty diaper. The first stools are black and sticky (meconium). Day 2: at least 2 wet and 2 dirty. Day 3: at least 3 wet and 3 dirty, with stools turning greener. Day 4: at least 4 wet and 4 dirty, and stools getting yellower. From day 5: at least 6 heavy wet diapers a day and typically 3 or more yellow, seedy stools a day in a breastfed baby.
Urine should be pale and almost odourless. Pink or orange brick-dust-like stains (urates) can be seen in the first days, but should be gone by about day 5. If they continue, tell your midwife or health nurse.
After the first weeks
From about 1 month, expect around 6 or more wet diapers a day. Stool patterns vary a lot. Many breastfed babies poop several times a day for the first 4 to 6 weeks, and then some switch to going every few days, or even once a week, with soft stools. If your baby is feeding well, gaining weight and the stool is soft, this can be normal.
Always check with your health nurse if you are unsure, especially if your baby is under 6 weeks old and has stopped passing stools.
Breastfed and formula-fed babies
Breastfed babies usually have loose, yellow, seedy stools that can look runny. Formula-fed babies tend to have firmer, tan or yellow-brown stools, and may poop slightly less often, often once or more per day. The number of wet diapers is a similar guide for both: at least 5 to 6 a day after the first week.
Disposable diapers can be hard to judge. If you are unsure whether a diaper is wet, lift it to feel the weight. For more on colours and what is normal, see our guide on baby poop colour and frequency.
Signs of dehydration and when to get help
Contact a health nurse, doctor or out-of-hours service the same day if your baby has fewer wet diapers than expected, dark yellow or strong-smelling urine, or no wet diaper for 6 to 8 hours. Other warning signs include a dry mouth, no tears when crying, a sunken soft spot (fontanelle) on the head, unusual sleepiness, being difficult to wake for feeds, and cool or blotchy skin.
Also seek advice for white, grey or very pale stools, black stools after the first days, or blood in the stool. If you are worried about milk supply, our guide on low milk supply has practical steps.
Frequently asked questions
How many wet diapers should a 1-week-old have?
From day 5, expect at least 6 heavy wet diapers in 24 hours, plus several yellow stools if breastfed. Fewer than this is a reason to contact your midwife or health nurse.
How many dirty diapers should a newborn have?
Roughly one more per day for the first four days, then at least 3 yellow stools a day in the first weeks for breastfed babies. After about 6 weeks, patterns vary widely.
Is it normal for a breastfed baby to poop only once a week?
It can be, after the first 4 to 6 weeks, if the baby is feeding well, gaining weight and the stool is soft. Check with your health nurse if you are unsure.
What are the signs my baby is dehydrated?
Fewer wet diapers, dark urine, dry mouth, no tears, sunken soft spot, unusual sleepiness. Contact a doctor the same day.
