The phrase "nighttime feedings" refers to the act of providing food or nourishment during the night. This term is commonly used in relation to infant care, where it means offering breast milk or formula to a baby during the hours between sunset and sunrise. Nighttime feedings are necessary for babies who are not yet able to go through an entire 24-hour period without eating, as they require nutrients to grow and develop properly. The frequency of nighttime feedings varies among individuals but is typically less frequent than daytime feedings or bottle feedings.
