Meconium is a newborn's first bowel movement. This sticky, thick, dark green substance is composed of cells, protein, fats, and intestinal secretions like bile.
Composition of Meconium
Meconium isn't like normal poop. It's made up of:
- Cells: Shed from the baby's intestinal lining.
- Protein: Essential building blocks for the body.
- Fats: Provide energy.
- Intestinal Secretions: Including bile, which aids in digestion.
When is Meconium Passed?
Typically, babies pass meconium in the first few hours and days after birth. However, some babies may pass meconium while still in the womb during late pregnancy. This can sometimes lead to complications during delivery, as the meconium can be inhaled.
