Question
My child has green stool. What could be the cause and how long might it last?
Answer
A baby’s green-colored stool can be normal. Breastfed babies usually have green or dark green stool, while formula-fed babies typically have yellow stool. Additionally, when a baby consumes new green vegetables or fruits in their complementary foods, the stool can also turn green. If the baby’s frequency and characteristics of defecation are not significantly abnormal, and the baby is in good spirits, eating well, without symptoms such as fever, cough, or vomiting, no special treatment is needed.
