The Mystery Of Newborn Poop: From Yellow To Green

when do newborns stop having seedy yellow poop

Newborns have very different poop schedules and consistencies compared to older children and adults. In their first few days of life, newborns pass meconium, a greenish-black, tarry, sticky poop. After this, the colour of their poop will change to green, yellow, or brown. Seedy yellow poop is common in breastfed babies, and is a sign that the baby is starting to digest breast milk or formula. This type of poop will have a sweet smell and a loose, watery, seedy, mushy, curdy, creamy, pasty, or lumpy texture.

Newborn poop frequency

The frequency of a newborn's poop varies, so don't be alarmed if your baby's poop schedule is unique. In the first few days after birth, newborns pass meconium, a sticky, tar-like substance that is black or greenish-black in colour. After this, the frequency and colour of a newborn's poop depend on whether they are breastfed or formula-fed.

Breastfed Newborns

Breastfed newborns typically have several bowel movements each day, with at least one poopy diaper for every day of life in the first five days. After this, the average breastfed newborn will have about five dirty diapers a day, though anywhere around several per day is normal. By six weeks old, breastfed babies' poop patterns may change, and they may start skipping a day or two 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.

Formula-Fed Newborns

Formula-fed newborns may have fewer bowel movements each day than breastfed newborns. 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. As long as their poop is soft and passed without a struggle, there is no need for concern.

When to Call a Doctor

If your baby hasn't pooped in four days, you should call your doctor as this could be a sign of constipation. You should also call your doctor if your baby's poop is white, black, or has blood in it.

Breastfed baby poop

Newborns have greenish-black, tarry, sticky poop called meconium, which is made up of amniotic fluid, mucus, skin cells, and other things ingested in the womb. During the first 24 hours, a newborn should produce at least one meconium stool. In the following 24 hours, they should have at least two poopy diapers, and by the third day, at least three. Meconium can be difficult to clean from a baby's skin, so olive oil is recommended for an easier clean.

After the first few days, a breastfed baby's poop will turn mustard yellow, green, or brown, with a seedy, pasty texture, resembling diarrhoea. It will also have a sweet smell, unlike regular bowel movement odour. The texture will be soft and somewhat runny, almost like pancake batter. Small amounts of mucus are also normal.

The frequency of a baby's poop varies, and breastfed infants tend to poop more frequently than formula-fed infants. However, if your baby hasn't pooped in four days, you should contact your paediatrician as it could be a sign of constipation.

As your baby starts eating solid foods, their poop will change colour and texture. This is normal, but certain colours can indicate your baby's health or signal a warning sign. For example, white or light grey baby poop could be a sign of a liver condition and an inability to digest food properly.

Formula-fed baby poop

Newborns have greenish-black, tarry, sticky poop called meconium, which is made up of amniotic fluid, mucus, skin cells, and other things ingested in utero. After birth, this meconium is passed within 24 hours, and the poop will transition in colour and texture, turning yellow or mustard in colour and having a runny consistency.

The colour of formula-fed baby poop can range from yellow-brown, tan-brown, to green-brown, and sometimes even darker green if your baby is receiving an iron supplement. It is important to monitor the consistency and colour of your baby's poop, as hard and pebble-like stools can indicate constipation, while watery stools can be a sign of diarrhoea and potential dehydration.

As your baby starts eating solids, their poop will become thicker, smellier, and may even have bits of undigested food in it. The colour may also become darker or lighter, depending on the types of solid foods introduced.

If you notice any concerning changes in your baby's poop, such as white or pale and chalky stools, it is important to contact your healthcare provider right away as it may indicate an underlying health issue.

Partially digested food in baby poop

It's normal to see changes in your baby's stool as they grow, start drinking breast milk or formula, and begin eating solids. However, some colour and consistency changes may indicate a health issue.

It's common to see partially digested food in your baby's poop, especially when they start eating solids. This is because not all food is completely digestible, and some food passes through the intestines so quickly that it doesn't break down entirely. This can result in your baby's poop having chunks of food or an unusual colour.

For example, foods high in insoluble fibre, such as corn, often pass through the body undigested. This is because corn has an outer shell made of cellulose, which the body cannot break down. While the body digests the inside of the kernel, the hard outer casing is expelled into the stool.

Other high-fibre foods that the body cannot fully break down include vegetable and fruit peels, and leafy green vegetables.

Newborns typically have greenish-black, tarry, sticky poop called meconium during their first few days after birth. Two to four days after birth, you'll notice "transitional stools" that are green and less sticky than meconium.

When your baby starts breastfeeding or drinking formula, their poop will turn green or yellow and have a more liquid consistency. Breastfed babies' poop will stay in the green-yellow-brown palette as long as they continue breastfeeding. Formula-fed babies' poop will be slightly lighter in colour but similar to breastfed babies.

When to be concerned

While changes in baby poop colour are normal, there are some colours and consistencies that may be cause for concern:

  • White or light grey baby poop could signal a liver condition and indicate that your baby is not properly digesting food.
  • Black blood in baby poop could be due to the baby having digested blood while breastfeeding on cracked and bleeding nipples. While this doesn't pose a threat to the baby, it's a good idea to check with a doctor to rule out something more serious.
  • Red blood in baby poop could be due to medications or certain foods consumed by the mother. It can also be a sign of a milk protein allergy or a bacterial infection.
  • Mucus in baby poop can be a sign of infection, although it may also occur when your baby is drooling.

Additionally, if your baby hasn't pooped in four days, you should call your paediatrician as this could be a sign of constipation.

Baby poop consistency

The consistency of a newborn's poop varies depending on whether they are breastfed or formula-fed. Breastfed babies tend to have mushy, seedy, and sometimes watery poop. Formula-fed newborn poop is thicker and more fully formed, with a consistency similar to peanut butter.

Around the third or fourth day of a newborn's life, they will start passing transitional stools, which are lighter in colour and loose and grainy in texture. This is a sign that the baby is starting to digest breast milk or formula and is transitioning to normal baby poop.

Breastfed babies may have poop that is mustard-like in colour, ranging from yellow to green or light brown. The consistency can be loose, watery, seedy, mushy, curdy, creamy, pasty, or lumpy. It also has a sweetish smell, unlike regular bowel movement odour.

Formula-fed babies' poop is usually pale yellow to tan-brown, sometimes with a greenish tinge. It is softer but better formed than that of breastfed babies. The odour is stronger, resembling regular poop but not as strong as when the baby starts eating solids.

Once solid foods are introduced, the baby's poop will change from soft and mushy to thick, dark, and smelly. It will become increasingly similar to adult poop as their diet includes more solid foods.

It is important to note that some variations in poop consistency are expected, but if the baby's poop strays too far from the normal textures, it may be a cause for concern. Very loose or watery stools for three or more diapers could lead to dehydration, while hard, pellet-like poop may indicate constipation.

Frequently asked questions

Newborns will start having seedy yellow poop around the third or fourth day of their life, after all the meconium (the first few sticky, tar-like, greenish-black poops) passes.

Meconium is the name given to a newborn's first few poops. They are thick, sticky, and greenish-black in colour, and are made up of cells, amniotic fluid, bile, and mucus that the baby ingested while in the womb.

Newborns tend to poop about once or twice a day, but this can increase to up to 5-10 times daily by the time they are one week old.
