What Does Your Baby's Poop Color Mean?

As a new parent, you quickly learn that baby poop has a wide array of colours, and each hue can tell you something about your baby's health. Understanding what different poop colours might indicate is an essential aspect of monitoring your baby's wellbeing. Here's an extensive guide to what various baby poop colours mean, including insights that could help you decide when a visit to the paediatrician might be necessary. 

What Do Different Baby Poop Colours Mean? 

Mustard Yellow:

For babies who are breastfed, mustard yellow is the most common colour of poop. It's usually soft, loose, and might have seed-like particles. This colour is normal and indicates that your baby is digesting breast milk well.

Dark Green:

In formula-fed babies, poop often turns dark green. This colour can also appear in breastfed babies given iron supplements or if the mother consumes a significant amount of green leafy vegetables. Dark green poop is typically thicker than that of breastfed babies. It's normal and not a cause for concern unless accompanied by other unusual symptoms.

Bright Green:

Bright green poop can occur in both breastfed and formula-fed babies. It could occur if the baby is eating too quickly, consuming a lot of lactose from milk (foremilk), and not getting enough of the fattier milk that arrives later in the feeding (hindmilk). It can also be a sign of a virus. If bright green stool persists, consult a paediatrician to rule out any digestive issues.


As babies start to eat solids, their poop typically transitions to brown. This is a normal development and indicates that your baby's digestive system is handling new foods. The consistency and exact shade of brown might vary depending on the diet.


Orange poop can be seen in babies who are just starting on solids. It's often a result of digesting food like carrots or sweet potatoes. It's generally nothing to worry about unless the stool seems unusually loose, or your baby shows discomfort.


Black stool in newborns during the first few days is called meconium and is perfectly normal. However, if black poop occurs after the meconium stage, it could indicate bleeding in the upper gastrointestinal tract. If your baby's poop is black (and it's not meconium), you should contact your paediatrician immediately.


White or very pale stool can indicate a bile duct blockage. Stools get their characteristic brown colour from bile, a digestive fluid produced by the liver. Lack of bile can indicate a serious problem, and white stool warrants an immediate call to your paediatrician.


Seeing red in your baby's diaper can be alarming. Red can signify that there is blood in the stool. This might be due to a milk allergy, a small anal fissure (crack), or something more serious like an intestinal infection. If you notice red poop, it's best to consult a paediatrician to understand the cause.

    When to Worry About Baby Poop Color 

    While variations in poop colour can be normal, certain colours might indicate health issues: 

    Black, White, or Red Poop:

    As mentioned, these colours can signify more serious conditions and should prompt an immediate call to your paediatrician. 

    Consistent Changes in Color:

    Sudden and persistent changes in stool colour can also be a sign of dietary reactions or health issues. 

    Accompanying Symptoms:

    If unusual poop colour is accompanied by other symptoms like fever, vomiting, lethargy, or irritability, it might be time to visit your doctor. 

    Tips for Monitoring Baby Poop 

    Keep a Diaper Diary:

    Track your baby's poop colours and textures to notice patterns or changes over time. 

      Notice Other Symptoms:

      Always consider the overall wellbeing of your baby. Are they feeding well? Do they seem unusually upset? These clues can help you determine if a poop colour is part of a larger issue. 

        Consult Your Pediatrician:

        When in doubt, always consult your pediatrician. They can provide guidance and peace of mind. 


          Monitoring the colour of your baby's poop is a practical way to keep tabs on their health. Most variations are normal, especially with changes in diet. But knowing what each colour can represent will help you take preventative measures for your child's health and make sure they get the right care when they do. Remember, you know your baby best, and noticing changes in their poop can be one of the first signs that they might need a little extra attention. 


          When to Worry About Baby Poop? 

            You should be concerned about your baby's poop if you notice any unusual characteristics that persist. These include black, white, or red stools, which can indicate internal bleeding or liver issues. Also worrisome are symptoms like consistent diarrhoea, constipation, or foul-smelling stools, especially if accompanied by other signs of distress such as fever, vomiting, or excessive fussiness. Any significant changes in your baby's stool habits or appearance that cause you concern are worth a discussion with your paediatrician. 

            What is Healthy Baby Poop? 

              Healthy baby poop varies depending on whether your baby is breastfed or formula-fed. For breastfed infants, it's typically soft, mustard yellow, and may contain small, seed-like particles. For formula-fed babies, the poop is often a bit firmer and can be tan, yellow, or greenish. A healthy poop shouldn't be overly smelly; it will have a mild odour that is not excessively unpleasant. 

              What Does Milk Allergy Poop Look Like? 

                Poop from a baby with a milk allergy can have several distinctive characteristics. It may be more frequent and appear looser than normal. Sometimes, it can contain mucus or be frothy. It might also be tinged with green or have streaks of blood, indicating irritation in the intestines caused by the allergic reaction. See a doctor for advice and assessment if you think your child may have a milk allergy based on the way their stool looks.
