Finally, newborns vary greatly in the total amount of time they spend sleeping. In the first few days, the average newborn sleeps between 16-18 hours a day (Iglowstein et al 2002). By four weeks, newborn sleep averages about 14 hours. But the range is considerable. Some four-week-old babies sleep as little as 9 out of 24 hours. Others sleep for 19 hours a day (Iglowstein et al 2002).
