Final answer:
A newborn typically sleeps about 17 hours per day with increasing wakefulness over time. Their sleep patterns are different from adults and include multiple sleep periods day and night.
Step-by-step explanation:
The newborn sleeps approximately 17 hours a day, with periods of wakefulness gradually increasing. It is a normal developmental stage for them to sleep most of the day and be awake during nighttime feedings. Newborns' sleep patterns differ significantly from adults, and they have frequent periods of sleep throughout the day and night.
