Your baby's poop gives important clues about digestive health, and its color, texture and frequency change with age and feeding. For the first 2 to 3 days, the poop is black-green and sticky. This is called meconium. Then a transition phase begins and the color turns greenish brown. In breastfed babies, poop is usually mustard yellow, soft and seedy. In formula-fed babies it can be darker and a bit thicker.
Shades of yellow, green and brown are usually normal. Green poop can come from feeding, fast digestion or iron-fortified formula. The colors that really need attention are white, clay-colored or very pale poop, black poop after the meconium stage, and red poop that contains blood. These colors can be a sign of a problem with the liver and bile ducts or the digestive system.
Texture matters too. Very watery, frequent poop can point to fluid loss, while hard, pellet-like poop can point to constipation. Watching changes over a few days tells you more than a single diaper. Feeding type also changes how poop is read: a texture that's normal for a breastfed baby may be judged differently for a formula-fed baby. That's why the analysis takes your baby's age and feeding into account together.

Frequently asked questions
What color should baby poop be?
Black-green, sticky meconium is normal for the first 2 to 3 days. After that, poop in breastfed babies is usually mustard yellow, soft and seedy. In formula-fed babies it can be yellow-brown or light brown and a bit thicker. Shades of yellow, green and brown are mostly normal. White, clay-colored, black or bloody poop means you should talk to a doctor.
What does green baby poop mean?
Green poop is often harmless. Fast digestion, getting a lot of foremilk while breastfeeding, iron-fortified formula or green vegetables can cause this color. If your baby is feeding well, gaining weight and content, there's usually no need to worry. If green poop comes with fever, vomiting, frequent watery poop, blood or fussiness, talk to your doctor.
Is white baby poop dangerous?
Yes, white, clay-colored or very pale poop is a sign to contact a doctor right away. This color can mean bile isn't reaching the gut and can be a symptom of liver problems such as a blocked bile duct. These conditions have better outcomes with early diagnosis. If you see pale poop, especially together with jaundice that lasts, see your doctor the same day.
What should I do if there is blood in my baby's poop?
If you see red blood or streaks of blood in the poop, talk to your doctor. It can come from something harmless like a small tear around the bottom, or from something that needs checking, such as a cow's milk protein allergy or an infection. If there is a lot of blood, or your baby is weak, feverish, vomiting or has a swollen belly, go to the emergency room without waiting. Showing the diaper or a photo of it to the doctor helps.
