Formula-Fed Newborns: Pooping Patterns And What To Expect

Newborns have very different toilet habits from adults, and their poop can tell you a lot about their health. For the first few days of their life, a newborn's poop will be a sticky, tar-like substance called meconium. After this, the frequency of their bowel movements will depend on whether they are breastfed or formula-fed. Breastfed newborns tend to have several bowel movements each day, whereas formula-fed newborns may have fewer. Formula-fed babies tend to have firmer, bigger poops than breastfed babies, and they may go longer without pooping.

How often newborns poop

Newborns typically pass meconium, a black, sticky, tar-like substance, in the first few days after birth. Meconium is made from swallowing amniotic fluid in utero and can contain shed skin cells, shed intestinal lining cells, mucus, and bile.

After the meconium has passed, the frequency of a newborn's bowel movements will depend on whether they are breastfed or formula-fed. It will also depend on the individual baby, as their unique digestive system will determine the consistency of their stool.

Formula-fed newborns typically have one to four bowel movements each day. Some formula-fed infants may poop much less frequently, and this is normal as long as they are still eating and gaining weight. Their poops tend to be yellow to brown in color and are firmer than those of breastfed babies.

Breastfed newborns tend to have several bowel movements each day, and many will poop after each nursing session. However, some breastfed newborns may only poop once every few days, especially after the first two weeks of life. Both situations can be healthy. Breastfed baby stools tend to be soft, seedy, and mustard-coloured.

Changes to Pooping Patterns

It is normal for the frequency of a newborn's pooping to slow around 6-8 weeks of age. After this time, newborns may only poop once or twice a week if they are maintaining a healthy weight.

When to Call a Health Care Provider

Although constipation is rare in newborns, there are some signs of a backed-up baby to look out for. These include hard or dried-out stool, crying and appearing uncomfortable, and stool containing blood.

If a newborn has diarrhoea, persistent constipation, or blood-tinged stools, contact a doctor.

Formula-fed newborn poop frequency

The frequency of a newborn's bowel movements can be an indicator of their overall health. It is important to monitor your newborn's diapers, as they can tell you a lot about their health and whether they are consuming enough milk.

Formula-fed newborns typically poop fewer times than breastfed newborns. On average, formula-fed babies have around one to four bowel movements per day, but some go as long as three or four days without a bowel movement.

Formula-fed baby poop is usually firmer and bigger than that of breastfed babies, with a stronger smell. It is typically yellow-brown, tan-brown, or green-brown in colour, and its consistency is similar to that of peanut butter.

When to be concerned about formula-fed newborn poop frequency

As long as your formula-fed newborn's poop is soft and passed without a struggle, there is usually no cause for concern. However, if your baby does not poop for more than five days, or if you notice any of the following, contact your paediatrician:

• Hard or dried-out stool consistency
• Strained facial expressions
• Crying and appearing uncomfortable
• Stool containing blood
• Fussiness and discomfort
• Spitting up more than usual

Changes in formula-fed newborn poop frequency

The frequency of your formula-fed newborn's poop may change as they grow and their diet changes. For example, once they start eating solids, their poop will become thicker and smellier, and you may even spot bits of undigested food in their stool.

Breastfed newborn poop frequency

The frequency of a newborn's bowel movements depends on whether they are breastfed or formula-fed.

Breastfed newborns typically have several bowel movements per day, and their stool will be soft to runny in consistency. It may also be watery and mustard yellow in colour, sometimes with small, white seed-like particles. This can change to a greenish-yellow or tan-brown colour as the baby starts eating solid foods.

Breastfed babies usually have at least one poopy diaper for every day of life during their first five days. After this, the average breastfed newborn will have about five dirty diapers a day, though anywhere from three to 12 per day is considered normal.

After six weeks old, breastfed babies' poop patterns may change, and they may start skipping days between bowel movements. Some babies will continue to poop several times a day throughout the first year, while others will go several days between dirty diapers.

If your breastfed baby is having fewer than three bowel movements a day, they might not be getting enough milk.

Formula-Fed Newborn Poop Frequency

Formula-fed newborns may have fewer bowel movements than breastfed babies. Their stool will usually be soft but more formed, and anywhere from pale yellow to yellowish brown, light brown or brownish green in colour.

Formula-fed babies typically poop three to four times a day, but some go as long as three or four days without a bowel movement.

Newborn poop colour

The colour of your newborn's poop will vary depending on their age, diet, and health. In the first few days after birth, a newborn's poop (meconium) is typically a thick, sticky, tar-like substance that is greenish-black in colour. This is normal and is composed of amniotic fluid, mucus, skin cells, and bile that the baby ingested in the womb.

After the first few days, the colour of a newborn's poop will start to transition. For formula-fed babies, the poop colour will usually be on the brown spectrum, ranging from yellow-brown, tan-brown, or greenish-brown. It is similar in consistency to peanut butter and may be firmer than the poop of breastfed babies. Formula-fed babies may also have thicker poop that is more pungent in smell.

For breastfed babies, the poop colour is typically mustard yellow or bright yellow and may have a mushy or creamy consistency. It may also be runny and seedy, resembling Dijon mustard. Breastfed babies may also have looser, runnier stools, which indicate that they are absorbing the solids in the breast milk.

As your baby grows and starts eating solids, the colour of their poop will change again. Solid food poop is usually brown or dark brown and thicker, with a stronger odour. You may also start to notice small pieces of undigested food in their poop.

It is important to monitor the colour and consistency of your newborn's poop, as it can indicate potential health issues. For example, white, red, or black poop outside of the first few days of life could signal a health problem. Red or maroon poop could indicate blood in the stool, while black stool could indicate bleeding in the digestive system. White or pale-coloured poop could be a sign of a liver or gallbladder problem.

If you notice any unusual colours or consistency in your newborn's poop, or if they are experiencing any other symptoms, it is important to consult with a healthcare professional.

Newborn poop consistency

The consistency of a newborn's poop varies depending on whether they are breastfed or formula-fed.

Formula-Fed Babies

Formula-fed babies typically have firmer and browner poop than breastfed babies. Their poop is usually a shade of yellow or brown and has a pasty consistency, similar to peanut butter. It is normal for formula-fed babies to pass fewer but bigger and smellier stools than breastfed babies.

After starting solids, the consistency of formula-fed babies' poop will become thicker and smellier. It may also become darker or lighter, depending on the types of solid food they are consuming.

Breastfed Babies

Breastfed babies usually have softer and runnier stools than formula-fed babies. Their poop is often yellow, seedy, and runny, with a mustard-like colour and consistency.

It is normal for breastfed babies to have looser stools, as it indicates that they are absorbing the solids in breast milk.

Meconium

Regardless of whether a newborn is breastfed or formula-fed, their first poop will be meconium—a sticky, tar-like substance that is greenish-black in colour. Meconium is made up of amniotic fluid, mucus, skin cells, and other things ingested in utero. Meconium is typically passed within 24 to 48 hours of birth.

After meconium, transitional stools will occur, which are dark, greenish-yellow, and loose. Transitional stools usually last for about three to four days before the baby's diet determines the colour and consistency of their poop.
