By the end of the first year, infants spend about ____ of the 24-hour period asleep, with most sleep at night and one or two naps during the day

Infants steadily consolidate sleep, with longer nighttime periods and shorter daytime naps as their sleep-regulation system matures. By the end of the first year, most babies need about 12 to 14 hours of sleep in a 24-hour day, with the bulk at night and one to two daytime naps. That total typically amounts to roughly half the day spent asleep, around 50–55% of a 24-hour period. Individual variation exists, but this range captures the common pattern at this age.
