A newborn’s poop at birth is normally dark green or dark green in color, and gradually changes to golden yellow or light yellow as the baby eats. Generally speaking, the newborn baby’s newborn stool is fetal stool, which contains amniotic fluid and fetal hair absorbed by the fetus in the mother’s body. At this time, the poop does not have an obvious unpleasant odor. Usually, the bowel movement is cleared within 3 to 4 days. When the newborn’s bowel movements are clean and breast milk or formula is slowly added, the color and character of the stool will change accordingly. Under normal circumstances, it will appear golden yellow or light yellow, thin paste, contrast fetal stools appear obvious sour taste. It is important to note that breastfed babies and formula-fed babies may show slight differences in stool characteristics. If your baby’s stool is not foamy, granular or smelly, or has blood in it, it is generally normal and parents need not worry too much. If your baby has black, watery or egg-like stools, or if there is blood in the stool, you should seek immediate medical attention.
