What's the reason for a 50-day-old baby having green poop?

1. In breastfed infants, excessive intake of green vegetables by the mother may lead to higher levels of chlorophyll in breast milk. 2. Imbalance in the infant's gut microbiota may result in incomplete digestion of food. 3. The infant may have mild indigestion or a gastrointestinal infection. 4. Parents are advised to monitor the baby's mental status, appetite, and frequency of bowel movements; seek medical attention promptly if any abnormalities occur. Meanwhile, the mother can appropriately adjust her diet and maintain good hygiene in the infant's feeding routine.
