When you break it down, newborn babies tend to do three things – eat, sleep and poop. And if you’ve recently become a parent, it may come as a shock to you just how many nappies your little one can get through a day.  

Newborn poop isn’t very much like its adult counterpart, which can take you by surprise when you first start changing nappies. Here’s everything you need to know about what’s normal and what’s not in the world of newborn baby poop. 

How often should a newborn poop?

While there isn’t an exact poop quota your baby should meet each day, on average, babies have about four poops a day during the first week of their life. This decreases to an average of two per day by their first birthday.  

Breast milk is considered a natural laxative, so breastfed babies may poop at every feed during their first few weeks. Thankfully, this 'in and out' phase doesn't last very long, and they might not poop for several days after the six-week mark. Formula-fed newborn babies, on the other hand, can poop up to five times a day. This reduces to as little as once a day after a few months.

While all of this might seem like too much poop to handle, there’s generally not a lot to worry about. Some babies are quite literally pooping machines, while others can go a few days without pooping at all!  

If your baby seems happy and is eating well, chances are things are fine (even if you need to change them 12 times a day), but it’s always best to trust your parenting instinct and speak to your GP, midwife, or health visitor if you're worried about your little one's bowel movements.

Types of newborn baby poop

There are different stages of baby poop, from meconium to normal newborn poop, and the colour and consistency may vary from day to day as their digestive system starts functioning. Let's run through each stage in more detail.

Meconium: Within 48 hours

Meconium is a baby's first poop and it's already in the bowel at the time of birth.

It’s dark, thick, and tarry, and can be sticky and very hard to clean up. It contains cells and other substances that line your baby’s digestive tract during pregnancy. This kind of poop usually subsides after three or four days. You should speak to your GP if your baby hasn’t passed any meconium 48 hours after birth.

Green poop: Day three to four

Greenish-coloured poop is usually a sign that the last of the meconium is leaving a baby's bowel. During this stage, their poop is still dark but has a green tinge as they start to digest milk.

Yellow poop: Day five to six

From around day five, your baby's poop may look like it has seeds in it. Newborn poo at this stage is usually runny, but not very smelly. If your baby is formula-fed their poop may have a slightly darker tan shade and might be a bit smellier!

Newborn poop colours and what they mean

A good indication of your baby’s digestive health is the colour of their poop!

  • Mustard yellow: Breastfed babies often poo yellow stools. The consistency will generally be loose (sometimes very loose!), and smell (semi) sweet – not like your average poop!  
  • Pale yellow or pale brown: Formula-fed babies might have semi-formed poops that are this colour, and they may strain a little to work this kind of poo out as it can be a little firm.
  • Green: While a few green nappies are usually nothing to worry about, babies who frequently poop green, watery stools might have diarrhoea. It could be a sign that your baby has an allergy or intolerance, so it’s best to check this one out with your health advisor.  
  • Pink or red: Red or pink baby poop could be a sign of blood, but there’s no need to panic if you spot it. See your doctor and they’ll be able to tell you what’s going on. It could be a sign of allergies or constipation. Alternatively, if you see blood in your baby's nappy, it could be harmless false or pseudo menstruation – a very light bleed from a baby girl's vagina that's caused by the effects of mum's hormones on their baby's system.
  • White: Very pale, white poop is very rare, but it could indicate an underlying problem. Contact your doctor straight away if you spot this kind of poop.

Signs of newborn diarrhoea 

As we’ve seen, newborn poops can vary hugely from baby to baby, week to week. If they’re eating well, gaining weight and growing, the chances are everything is fine.  

It’s not unusual for a breastfed baby’s poop to be loose, but if they’re frequently passing watery stools, it could be a sign of diarrhoea.  

What can cause diarrhoea in newborns?  

Diarrhoea can be a symptom of many things, including:  

  • Infection  
  • Teething  
  • Antibiotics 
  • Dietary changes  
  • Allergies  

It’s always best to get your baby checked out by a doctor if they have diarrhoea, to find out the root cause of their symptoms.  

Remember, if your baby has diarrhoea, it’s important to keep an eye on their fluids. You may need to breastfeed more frequently (or offer them the bottle more often), to help them get the extra fluids they need to avoid dehydration.  

Newborn struggling to poop  

Your baby might be constipated if they have any of the following symptoms:  

  • Pooping less than 3 times a week 
  • Hard, dry and lumpy poops that look like pellets 
  • They’re eating less, and aren’t as hungry  
  • Their tummy feels firm  
  • Their poops are larger than usual, and are difficult to pass  
  • They seem a little grizzly and fatigued.  

What can cause constipation in newborns? 

There are a few reasons why your baby could be constipated, but the most common are:  

Changes in diet: It’s not unusual for your baby to become constipated when they first start formula-feeding, or when you start introducing solid foods. There’s no need to worry, it’s just their body learning how to digest new things.  

Dehydration: Constipation can be caused by a lack of fluids. There are many reasons for this, including:  

  • They may find it uncomfortable to feed while they’re teething  
  • Illnesses, like a cold, or a throat or ear infection  
  • If you’ve begun to introduce solid foods, they may not be drinking enough fluids alongside their food. 

How do you help a newborn poop?  

It’s never easy to see your baby in pain or discomfort. The good news is there’s a few things you can do to help relieve their constipation:  

  • Keep them hydrated: If you’re formula feeding, offer them small sips of cooled, boiled tap water between their bottle feeds to prevent dehydration. If you’re breastfeeding, continue to offer lots of feeds (breastfed babies don’t need to drink additional water between feeds).  
  • Bicycle legs: Just like adults, movement can help keep things regular for babies. Try lying your baby flat and gently moving their legs in a bicycle motion, to help relieve constipation.  
  • Baby massage: This is a lovely way to bond with them and can also help relieve constipation. Try rubbing their tummy clockwise, in slow downward strokes (make sure your baby is laying on their back, on a soft, safe and comfortable surface).  
  • A nice, warm bath: Warm water can help relax their abdominal muscles, discourage them from straining and soothe some of their discomfort.  
  • Check their formula: Using too much formula powder when preparing a bottle can reduce the amount of water your baby drinks and therefore lead to constipation. We recommend that you always follow the manufacturer's guidelines when preparing a bottle of formula for your baby. 

Nappy cream for newborns  

Pooping problems can lead to irritation around your baby’s nappy area. Nappy rashes are super common (so no need to panic!) but they can be very uncomfortable. 

If your baby already has a nappy rash causing them discomfort, you should use a nappy rash cream to treat it. It’s best to ask your health visitor or a pharmacist to recommend the best product for this.  

How often should a newborn baby pee?

There isn’t an ideal number of urinations for a newborn baby, but if their nappy is wet regularly, that’s a good sign.  

On average, a newborn baby’s first week might look like this:  

  • (24 hours after birth): Typically, 1 wee a day  

  • (Day 1 to 2): Typically, 2 or more wees a day  

  • (Day 3 to 4): Typically, 3 or more wees a day 

  • (Day 5 to 6): Typically, 5 or more wees a day  

The term ‘heavy nappy’ means a nappy full of wee or poop, that’s due for a change. 

While newborn baby poo can be softer in consistency than its adult counterpart, watery poo may be a sign of diarrhoea. 

If you think your baby has diarrhoea, it’s best to take them to see a doctor (young babies can become dehydrated very easily, especially if they’re under 6 months old).
