Final answer:
Newborns typically have Transitional stools during the transitional period; these are characterized as greenish-brown and more formed. They signify the progression from meconium to regular stools and are crucial for reducing the risk of complications such as hyperbilirubinemia.
Step-by-step explanation:
The type of stools that newborns typically have during the transitional period, characterized as greenish-brown and more formed, are D) Transitional stools. These occur after the newborn's first stools, which are composed of meconium, and before the establishment of regular breast milk or formula stools. Transitional stools indicate that the baby's digestive system is starting to process the breast milk or formula, and meconium is being cleared from the system. These stools are part of the normal process as the infant's digestion transitions from the sterile in-utero environment to feeding outside the womb.
It's important during this period to ensure that meconium is expelled properly to prevent hyperbilirubinemia, a condition where high levels of bilirubin can lead to jaundice. Meconium aspiration can occur if the baby passes meconium before or during birth, which can lead to complications such as respiratory distress and infection. Regular passing of stools helps clear meconium and minimize the risk of jaundice.
