How many daily feedings are considered normal for a newborn?

  1. 8 to 10
  2. 10 to 12
  3. 6 to 8
  4. 12 to 14

Answer(s): B

Explanation:

An average newborn’s stomach empties every 1.5 hours, so common feeding times occur about every 2 hours during a 24-hour period; therefore, 10 to 12 feedings per day is typical.
Frequent breastfeeds increase a mother’s prolactin levels, and high prolactin levels are required to establish an adequate milk supply.
A higher-frequency of feedings help babies compensate for the lower caloric density of the milk.
