Newborn babies must adjust to a new environment, and it takes time to adapt to life outside of the womb. While it may be concerning, infrequent bowel movements are common in newborns. Diet can also affect this process. Understanding what constitutes normal and abnormal bowel movements in your baby can help you avoid unnecessary worrying and know when to seek medical advice.


1. Baby's First Stool

In the first hours of life, a newborn's body undergoes many changes to adapt to life outside the womb. One such change takes place in the digestive tract. A healthy baby will expel the first stool, called the meconium, within one day of birth. The meconium is a thick black or dark green mixture of amniotic fluid, intestinal lumen, mucus, and other substances that baby ingested in utero and may last for a few days after birth.
