What is the average amount of sleep for a newborn?

Newborns typically require a significant amount of sleep to support their rapid growth and development. On average, they sleep around 16.5 hours a day. This sleep pattern is essential as it allows their bodies and brains to rest, process new experiences, and engage in critical developmental processes, such as growth and brain maturation.

In the context of infancy, sleep is also fragmented, meaning that newborns do not experience long stretches of uninterrupted sleep. Instead, they wake frequently to feed, which complements their need for nourishment and reinforces their body's developmental needs. Thus, 16.5 hours represents a reasonable average, accommodating both their requirements for rest and the behavioral patterns typical in newborns.

Other potential answers, while they indicate varying amounts of sleep, do not align closely with the researched averages documented in child development literature. For instance, amounts like 8 or 12 hours are insufficient for the energy and growth demands placed on newborns, while 20 hours, although plausible for some individual cases, exceeds the average seen in broad populations of infants.
