Potential evapotranspiration (PET) is the amount of water that would be evaporated and transpired if there were sufficient water available. This demand incorporates the energy available for evaporation and the ability of the lower atmosphere to transport evaporated moisture away from the land surface.
In many cases of hospital births where the baby has passed meconium before birth, a special NICU team will be called when the baby is delivered in case there was ingestion of the meconium into the babyâs lungs. If a newborn does swallow some meconium it can lead to Meconium aspiration syndrome (MAS).
The number and type of movements your baby has will indicate whether he's getting enough to eat. During the meconium phase (the first few days after birth), your baby may have four or five tarry, dark, greenish-black stools spread out over two or three days. As your colostrum develops into mature milk, he should have at least two to five bowel movements in a 24-hour period for the first six weeks.
