waste material that passes from baby to mother
Meconium Meconium is normally retained in the infant's bowel until after birth, but sometimes it is expelled into the amniotic fluid (also called "amniotic liquor") prior to birth or during labor and delivery. The stained amniotic fluid (called "meconium liquor" or "meconium stained liquor") is recognised by medical staff that this may be a sign of fetal distress. Some post-dates pregnancies (where the woman is more than 40 weeks pregnant) may also have meconium stained liquor without fetal distress. Medical staff may aspirate the meconium from the nose and mouth of a newborn immediately after delivery in the event the baby shows signs of respiratory distress to decrease the risk of meconium aspiration syndrome.
Don't throw the baby out with the bathwater This idiom derives from a German proverb, das Kind mit dem Bade ausschütten. The earliest record of this phrase is in 1512, in Narrenbeschwörung (Appeal to Fools) by Thomas Murner; and this book includes a woodcut illustration showing a woman tossing a baby out with waste water. It is a common catchphrase in German, with examples of its use in work by Martin Luther, Johannes Kepler, Johann Wolfgang von Goethe, Otto von Bismarck, Thomas Mann, and Günter Grass.[6][7]
