fluid?
In utero, the mouth does work. The baby swallows the amniotic fluid, and pees it back out. For nutrition, the baby relies solely on the mother. The umbilical cord contains two arteries and a vein. The cord connects to the placenta, with the placenta being an organ with a side connected to mom and a side connected to the baby. The placenta is rich in blood supply. The mom's blood carries nutrients and oxygen to the placenta, where they are picked up by the baby's cord and carried to the baby. The baby carries waste products (like carbon dioxide) to the placenta, where the mom's blood picks them up and carries them away. The fetal lungs are not used in utero, although near the due date, the fetus starts to "practice" breathing movements. When the baby is born and the cord is cut, a rapid change in the baby's body begins. The lungs fill with air and start to work, and the baby becomes able to eat with its mouth and get rid of wastes into the diaper.
