Newborn Poop: What's Normal And What's Not?

Newborn poop can be a source of fascination and concern for new parents. It's not uncommon for parents to have questions about their baby's stool, including its frequency, colour, consistency, and smell.

Breastfed babies typically have soft, runny, and seedy poop with a mustard-like consistency and a slightly sweet smell. The seeds in the stool are undigested milk fat, which is entirely normal. Formula-fed babies, on the other hand, tend to have thicker and darker poop, often described as having a peanut butter-like consistency.

The colour of a baby's poop can vary and is usually influenced by their diet. For example, green poop can be caused by a foremilk/hindmilk imbalance in breastfed babies, while darker green poop in formula-fed babies can be due to iron supplements or the presence of iron in the formula. Red poop is often caused by red foods or medications, but it can also indicate bleeding in the gastrointestinal tract or allergies. White, grey, or clay-coloured poop may be a sign of liver problems and should be addressed with a doctor.

While the frequency and consistency of a baby's poop can vary, it's important to monitor for any signs of constipation or dehydration. If a baby hasn't pooped in four days, it's a good idea to consult a doctor.

Breastfed babies' poop is often seedy and yellow

It is normal for breastfed babies to have seedy and yellow poop. This is because breast milk is more easily digested than formula, leaving behind little "seeds" of undigested milk fat. These seeds are entirely normal and nothing to worry about. In fact, they are a sign that your baby is getting enough milk fat, which is important for their development.

Breastfed baby poop is typically loose, runny, and grainy or seedy. The seeds are those little bits of undigested milk fat. The colour of breastfed baby poop is usually a mustard or bright yellow, and sometimes it can have a slight orange tint. This colour is due to the presence of bile, a fluid made in the liver that aids digestion.

Breastfed babies tend to poop more frequently than formula-fed babies, especially in the early days after birth. This is because breast milk is so nutritious that the body absorbs most of it, leaving very little waste. However, it is still normal for breastfed babies to go up to seven days without pooping, as long as they are not in any pain and the stools are soft.

When to Be Concerned

While seedy and yellow poop is normal for breastfed babies, there are some things to watch out for. If your baby's poop is consistently watery or runny, it could lead to dehydration. On the other hand, if the poop is hard and pellet-like, it could be a sign of constipation or lactose intolerance. If you notice any blood in your baby's poop, this could be a sign of allergies or bleeding in the gastrointestinal tract, so be sure to call your doctor.

Seedy poop is a result of undigested milk fat

Newborn poop can vary in texture and colour, and it is important to monitor your baby's stool as it can be indicative of their health.

Breastfed babies tend to have looser stools than formula-fed babies, and their poop is often described as grainy or seedy. This is because breast milk is more easily digested than formula, and the fat content can sometimes be left undigested.

The seeds in a baby's stool are a good indicator that they are getting enough fat in their diet and are digesting their food properly. It is important to note that seedy poop is not a cause for concern unless it is accompanied by other symptoms such as diarrhoea, constipation, or abdominal pain.

If you are concerned about your baby's poop, it is always best to consult your paediatrician or doctor. They will be able to advise you on whether the seedy texture is normal for your baby's diet and age.

Newborns may poop multiple times a day or once every few days

Breastfed babies may go two to three days without pooping, and it is possible for them to go up to seven days without a bowel movement. As long as they seem content and their bellies are soft, they are likely fine. However, if their bellies feel rigid, or they seem uncomfortable, or their poop is hard, it could be a sign of constipation.

Formula-fed babies tend to have darker and firmer poop than breastfed babies, and they may poop at least once a day. If they don't poop for two or more days, it could be a sign of constipation or an allergy, and it is important to address this with the doctor.

Meconium is the name for a newborn's first poop

Meconium starts to build up inside the baby's intestines when they begin to practise drinking amniotic fluid in the womb. It is ideal for the baby to pass meconium shortly after birth, but it is not uncommon for some fetuses to pass meconium before birth. While swallowing meconium is safe, inhaling it can cause serious respiratory problems and conditions such as Meconium Aspiration Syndrome (MAS).

After the meconium has passed, the baby's poop will change in colour, consistency, and smell. Breastfed babies typically have softer stools that may be seedier, while formula-fed babies have thicker stools.

Meconium is black and sticky

Meconium is the name given to a newborn baby's first poop. It is dark, thick, and sticky, with a tar-like consistency and a blackish-green colour. It is composed of water, cells, hair, mucus, and other materials ingested by the baby in the uterus, such as amniotic fluid, bile, and intestinal epithelial cells.

Meconium is typically passed within the first few hours or days after birth, but it can also be expelled while the baby is still in the uterus. It is normal and safe for a baby to swallow meconium, but breathing it in can cause serious respiratory problems, a condition known as Meconium Aspiration Syndrome (MAS). MAS can cause respiratory distress, infection, and, in rare cases, death.

Meconium staining, or the presence of meconium in amniotic fluid, occurs in 12-20% of deliveries and is more common when a pregnancy goes beyond the due date. It is recognised by medical staff as a possible sign of fetal distress, and they will check the baby for respiratory issues after delivery.

Meconium should be completely passed by the end of the first few days after birth, with the stools progressing to a more typical yellow colour. Failure to pass meconium within 48 hours can indicate intestinal blockage, an underdeveloped rectum, or Hirschsprung disease.
