If meconium is present in the amniotic fluid, this is known as meconium aspiration or meconium aspiration syndrome (MAS). Your newborn can also breathe in amniotic fluid containing meconium shortly after birth. Although MAS is often not life threatening, it can cause significant health complications for your newborn.
It is first made up of water that is provided by the mother, and then around 20 weeks fetal urine becomes the primary substance. As the baby grows he or she will move and tumble in the womb with the help of the amniotic fluid. In the second trimester the baby will begin to breathe and swallow the amniotic fluid.
