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.
From around 16 weeks of pregnancy, the babyâs kidneys begin to function, and fetal urine becomes the main source of amniotic fluid. The other source of amniotic fluid is fluid excreted from the babyâs lungs. Initially, the amniotic fluid is absorbed by the babyâs skin and tissue.
