average sleep time for babies
The sleep charts that you see in parenting books and websites are based on how much time parentsâtypically, Western parentsâsay their babies spend sleeping. For instance, studies of Australian babies reveal that the average newborn gets about 16-17 hours of sleep over a 24-hour period.f course, not all of this sleep time occurred at night. One-month-old babies slept an average of 8 hours each night, with 96% of babies getting between 6 and 13.3 hours of nighttime sleep. At 3 months, babies spent more time sleeping at nightâ-10 hours, on average.
