By Age

What to expect by age

0-3 months

Newborn stools progress from black meconium to transitional green-brown to yellow (breastfed) or tan-brown (formula-fed) within the first week. Breastfed baby poop is typically yellow, seedy, and loose. Formula-fed poop is usually tan, thicker, and more formed. Green stool is common and almost always normal.

3-6 months

Stool color may vary day to day and is influenced by what the baby (or breastfeeding mother) eats. Green stools can occur with fast gut transit, foremilk-hindmilk imbalance, or mild illness. Orange stool is often from beta-carotene in formula or breast milk. All of these are normal.

6-12 months

With the introduction of solids, stool colors change dramatically based on foods eaten. Orange from carrots and sweet potatoes, green from peas and green vegetables, red from beets and tomatoes, and dark from blueberries are all normal food-related changes.

12-24 months

Toddler stool colors continue to reflect dietary intake. The two stool colors that always warrant medical attention are white/chalky/pale grey stool (call your pediatrician the same day) and persistently black, tarry stool not explained by diet or iron.

Green Poop in Babies

Green poop in babies is almost always completely normal and nothing to worry about. It can be caused by iron in formula or supplements, a foremilk-hindmilk balance in breastfeeding, dietary changes, or simply normal variation in how quickly food moves through the gut.

Baby Black Poop

Black poop in a newborn's first few days (meconium) is completely normal and expected. Black or very dark green stools can also be caused by iron supplements or iron-fortified formula. However, black tarry stools outside of the newborn period that are not explained by iron can indicate digested blood from higher in the digestive tract and should be evaluated by a doctor promptly.

Baby White or Pale Poop

White, pale, chalky, or clay-colored stool in a baby is a MEDICAL EMERGENCY that requires immediate evaluation. Normal stool gets its color from bile, which is produced by the liver. White or very pale stools can indicate that bile is not reaching the intestines, which may be a sign of biliary atresia, a serious liver condition that requires urgent surgical treatment within the first weeks of life for the best outcomes.

Baby Orange Poop

Orange poop in babies is almost always completely normal and harmless. It is most commonly caused by the natural pigments in foods like carrots, sweet potatoes, squash, and other orange or yellow fruits and vegetables. In younger babies, orange stools can simply be a normal variation related to bile and how quickly food moves through the digestive tract.

Baby Poop Color Changes with Solids

Dramatic changes in poop color after starting solids are completely normal and expected. What your baby eats directly affects stool color - carrots may turn poop orange, spinach makes it green, beets can make it reddish, and blueberries can turn it dark blue-black. As long as your baby is comfortable and the stool is not white, black (tarry), or bright red with blood, these color changes are harmless.

My Baby's Belly Looks Swollen

A rounded, slightly protruding belly is completely normal in babies and toddlers due to immature abdominal muscles and their proportionally larger organs. However, if the belly becomes suddenly swollen, feels hard and tight, or is accompanied by pain, vomiting, or changes in bowel movements, it needs medical evaluation as it could signal gas buildup, constipation, or rarely, something more serious.
