The baby may poop inside the mother’s tummy, and this needs to be decided on a case-by-case basis. Most babies usually do not poop when they are in their tummies because when the baby is still a fetus, excretions are mainly through the umbilical cord and then from the mother, and only after birth will they officially start pooping. However, a small percentage of babies may poop in their mother’s stomach and may contaminate the amniotic fluid, resulting in a life-threatening situation for the baby. Parents who want to know if their baby has pooped in the mother’s stomach can observe the baby’s condition in the mother’s body through amniocentesis. If the color of the amniotic fluid is cloudy and dark green, the baby may have pooped inside the stomach, which means that the amniotic fluid has been contaminated, and it is necessary to go to the hospital in time for the relevant treatment.
