Poop Problems: Are Chunks In Newborn Poop Normal?

Newborns have very different poop from older babies and children. In their first few days after birth, a newborn's poop is greenish-black, tarry, and sticky, resembling motor oil. This is called meconium and is made up of amniotic fluid, mucus, skin cells, and other things ingested in utero. After a few days, the poop becomes lighter in colour, transitioning to yellow/green, tan, or mustardy yellow, and less sticky. This is a sign that the baby has started digesting early breast milk or formula. Once a baby starts eating solid foods, their poop will become firmer, browner, and smellier, and may contain chunks of undigested food.

Newborn poop colour

The colour of a newborn's poop can be surprising for new parents, but it's important to know what's normal and what might signal a problem. Here's a guide to newborn poop colour and what it can tell you about your baby's health:

Meconium

The first poop your baby passes is called meconium, and it is typically greenish-black and tarry in appearance. Meconium is made up of amniotic fluid, mucus, skin cells, and other things ingested while in the womb. It is normal for meconium to be thick, sticky, and difficult to clean off. Within the first few days of life, meconium will gradually change colour, transitioning from black to dark green, then to yellow.

Breastfed Baby Poop

Breastfed babies usually have poop that is mustard yellow, green, or brown in colour. It often has a seedy, pasty, or mushy texture and may even resemble mild diarrhoea. Breastfed baby poop typically has a slightly sweet odour. It is normal for breastfed baby poop to vary in shade, and it may be dotted with little seed-like flecks.

Formula-Fed Baby Poop

Formula-fed babies tend to have thicker, pastier poop that falls on the brown colour spectrum, ranging from yellow-brown to tan-brown or greenish-brown. Formula-fed babies also tend to have fewer bowel movements, and their stools are usually bigger and smellier than those of breastfed babies.

Transitional Stool

As your baby transitions from meconium to regular poop, their stool may be brown, yellow, or green. This is a sign that your baby has started digesting breast milk or formula, and their intestinal tract is functioning properly.

Orange, Yellow, and Brown Baby Poop

Baby poop that is orange, yellow, or brown is completely normal for both breastfed and bottle-fed babies.

Black Baby Poop

Black baby poop in the first few days of life is normal and is a result of meconium passing. However, if black poop persists beyond the first week, it could indicate bleeding in the digestive system, and medical advice should be sought.

Green Baby Poop

Green baby poop is usually normal and can be caused by various factors such as slow digestion, green foods in the diet of the mother, a cold, a stomach bug, food allergy, antibiotics, or treatment for jaundice. If your baby is gaining weight and seems content, green poop is typically not a cause for concern.

Red Baby Poop

Red poop is typically a sign of blood in the stool and requires medical attention. It could be caused by cracked or bleeding nipples if the mother is breastfeeding, or it could indicate a health problem.

White or Pale Baby Poop

White or pale-coloured poop is uncommon and could indicate a liver problem, such as biliary atresia, which is a blockage in the tubes that carry bile from the liver to the gallbladder. Pale-coloured poop, especially in newborns, should be addressed by a doctor.

Frequency of newborn pooping

The frequency of newborn pooping varies, so don't be alarmed if your baby poops as often as every feeding or as infrequently as every two to three days. Breastfed infants tend to poop more frequently than formula-fed infants.

Newborns usually have one or more bowel movements daily, and some newborns produce five or more dirty diapers a day in their first few weeks of life. Newborns and young infants tend to have several small poops in a row, so it's best to give them time to finish before changing their diapers.

Breastfed newborns often poop after every feeding (roughly six to ten times a day), but after three to six weeks, they typically slow down and start having bowel movements less frequently. Some breastfed babies may have just one bowel movement a week. This is because breast milk passes through the baby's digestive system without leaving much solid waste.

Formula-fed babies can also range from several bowel movements a day to several days between bowel movements once they're a month or two old. Their stools are usually bigger and smellier than those of breastfed babies.

If your baby hasn't pooped in four days, you should call your pediatrician. This could be a sign of constipation.

Newborn poop texture

The texture of a newborn's poop can vary depending on their age, diet, and feeding method. Here are some things to know about newborn poop texture:

Meconium

During the first few days after birth, a newborn's poop will be greenish-black, tarry, and sticky, resembling motor oil. This is called meconium and is made up of amniotic fluid, mucus, skin cells, and other things ingested in utero. Meconium is hard to clean and often requires petroleum jelly to protect the baby's bottom.

Transitional Stools

Two to four days after birth, the poop will transition to "transitional stools," which are lighter in colour, ranging from dark green to yellow-green, tan, or mustardy yellow. These stools are less sticky than meconium and indicate that the baby has started digesting early breast milk or formula.

Breastfed Baby Poop

Breastfed babies typically have poop with a mushy or creamy consistency. It can be runny, resembling mild diarrhoea, or like Dijon mustard and cottage cheese mixed together. It often has a seedy, pasty texture and a slightly sweet odour.

Formula-Fed Baby Poop

Formula-fed babies tend to have thicker, pastier stools, similar to peanut butter, in shades of yellow or brown. Their poop is usually bigger and smellier than that of breastfed babies.

Solid Foods

Once a baby starts eating solid foods, their poop will become firmer, browner, and smellier due to the healthy bacteria breaking down the food in their intestines. It is common to see identifiable chunks of food in their poop, as certain foods may not be fully digested or may pass through the intestines too quickly.

Variations and Warning Signs

While variations in poop texture and colour are usually normal, there are some warning signs to watch for. Consult a doctor if you notice any of the following:

• Watery, runny poop, which may indicate diarrhoea
• Hard, pebble-like poop, which could be a sign of constipation
• Bloody poop, which may indicate an intestinal infection or allergy
• White, clay-coloured, or pale yellow poop, which could signal liver or gallbladder problems
• Persistent changes in texture or colour, especially if accompanied by other symptoms such as fever, irritability, or abdominal pain

Newborn poop consistency

Newborns typically have their first bowel movement within 24 hours of birth. This first poop is known as meconium, a greenish-black, tarry, and sticky substance that resembles motor oil or thick tar. It is composed of amniotic fluid, mucus, skin cells, and other substances ingested in utero. Meconium is challenging to clean and tends to harden on the baby's bottom.

After the initial meconium, newborn poop transitions in colour and consistency over the next few days. This transitional stool indicates that the baby has started digesting early breast milk or formula, and their intestinal tract is functioning correctly. The poop becomes lighter in colour, progressing from dark green to yellow-green, tan, or mustard yellow, and has a less sticky texture.

Breastfed newborns often have a mustard yellow, green, or brown poop with a mushy or creamy consistency. It may resemble mild diarrhoea but is typically similar to a mix of Dijon mustard and cottage cheese, with little seed-like flecks. On the other hand, formula-fed babies tend to have pasty, peanut butter-like poop in shades of yellow-brown, tan-brown, or green-brown.

As newborns grow and their digestive systems develop, the consistency of their poop becomes firmer and thicker. Once solid foods are introduced, their poop becomes browner and smellier due to the healthy bacteria breaking down the food in their intestines. It is not uncommon to find identifiable chunks of food in their poop, as certain foods may not be fully digested or may pass through the intestines too quickly.

While newborn poop consistency can vary, it is important to monitor for any sudden changes or signs of discomfort in the baby. Hard, pebble-like stools, for example, may indicate constipation, and watery, runny poop could be a sign of diarrhoea. If you notice any unusual changes in the consistency of your baby's poop, it is always best to consult with a healthcare professional.

Newborn poop and diet

What to Expect from Newborn Poop

Newborns typically have their first bowel movement within 24 hours of birth. This first poop, known as meconium, is a greenish-black, tarry, sticky substance that resembles motor oil. It is composed of amniotic fluid, mucus, and skin cells ingested in utero. After a few days, the colour transitions to yellow/green, tan, or mustardy yellow, and the consistency becomes less sticky. This indicates that the baby has started digesting breast milk or formula.

Breastfed Baby Poop

Breastfed baby poop is typically mustard yellow, green, or brown, with a seedy, pasty texture that may resemble mild diarrhoea. It often has a slightly sweet odour. The texture can vary depending on the mother's diet, with some breastfed babies having greener poop if the mother has eaten something different.

Formula-Fed Baby Poop

Formula-fed babies tend to have thicker, pasty, peanut butter-like poop in shades of yellow-brown, tan-brown, or green-brown. It has a stronger odour than breastfed baby poop but is less pungent than that of babies eating solid food.

Solid Food and Baby Poop

The introduction of solid foods leads to noticeable changes in a baby's poop. It becomes thicker, browner, and smellier due to the presence of healthy bacteria breaking down food in the intestines. Chunks of undigested food may also be present, especially if the baby consumes a lot of one type of food or doesn't chew it completely.

When to Be Concerned

While newborn poop can vary in colour and consistency, there are some signs that may indicate a problem. White, grey, or pale-yellow stools, for example, can suggest a liver or gallbladder problem, such as biliary atresia. Black or red poop can also be a cause for concern, as it may indicate bleeding in the gastrointestinal tract or an allergy. If you notice any unusual colours, consistency, or other concerning symptoms, it is best to consult a healthcare professional.
