In the first few weeks, infants have no established day-night cycle and may wake every 2-3 hours to feed. By 3-4 months, many infants start to develop a more regular sleep pattern, with longer stretches of nighttime sleep. By 6 months, a typical infant may sleep about 11-12 hours at night with 2-3 daytime naps, totaling around 14 hours of sleep per day.
