How far back does baby stool go?

Baby stool can vary significantly based on the infant's diet and age. In the first few days after birth, newborns typically pass meconium, a thick, dark green substance that is composed of amniotic fluid, bile, and other materials ingested in the womb. As they transition to breast milk or formula, their stool changes in color and consistency. Generally, baby stool is analyzed for health indicators, but the specific time frame regarding its composition can vary based on individual circumstances.
