Development of a Baby's Digestive System in the Womb 

5 weeks

The digestive system of a baby's begins to develop around 5 weeks in the womb and continues to develop throughout the third trimester.


The umbilical cord and placenta allow the newborn to absorb nutrients from the mother.


Babies do not feed in the womb in the conventional sense, but they do absorb all required nutrients through the placenta


Babies usually do not pee in the womb, but they do acquire meconium, which is their first bowel movement after birth


Key nutrients like folic acid, iron, and calcium might help the baby's digestive system develop properly.

Second Trimester

The digestive system begins to function during the second trimester, and the baby's sucking reflex develops.


Peristalsis, or the wave-like motions that drive food through the digestive system, occurs between the ages of 14 and 23 weeks.


The baby's body begins to absorb minerals from the digestive tract during the third trimester and prepares for independent digestion after delivery.


Meconium, the baby's first bowel movement, is normally evacuated shortly after delivery and is made up of amniotic fluid, mucus, lanugo, bile, and shed cells.
