For babies over 6 months, the amount of nighttime sleep stayed fairly constant across agesâabout 11 hours on average, with a range of approximately 9-13 hours (Iglowstein et al 2003). Baby sleep requirements are also met by sleeping during the day.
There is no magic ânumber of sleep hoursâ that works for everybody of the same age. Babies initially sleep as much as 16 to 18 hours per day, which may boost growth and development (especially of the brain). School-age children and teens on average need about 9.5 hours of sleep per night.
