Looking for tweets for meconium.

frogapplause Meconium is normally stored in the infant's intestines until after birth, but sometimes (often in response to fetal distress) it is expelled into the amniotic fluid prior to birth, or during labor. If the baby then inhales the contaminated fluid, respiratory problems may occur.
See Meconium Aspiration Syndrome".
When a woman's water breaks, it should be fairly clear. If it's greenish or dark... that's an indication that meconium is present (meconium staining). This requires a doctor's attention. May 14, 2011

john "The kidneys are functioning, but for the first few days after delivery, the baby will not have many wet diapers. The frequency of wet diapers increases by the end of the week. The digestive system is working and the first bowel movement will be the sticky, dark, tarlike stool called meconium."
