0-4 weeks	35-60 min	Many short naps, no pattern	14-17 h

2-3 years	5-6 h (one nap)	1; some drop it before 3	11-14 h (10-13 h from age 3)

Total-sleep ranges are AASM/NSF consensus; wake windows and nap counts are common practice, not official standards.

Typical ranges

• 0-4 weeks: awake about 35-60 minutes at a time; many short naps with no pattern; 14-17 hours total.
• 1-2 months: awake 60-90 minutes; 4-6 naps; 14-17 hours.
• 3-4 months: awake 75 minutes to 2 hours; 3-5 naps; 14-17 hours, moving toward 12-16.
• 5-6 months: awake 2-3 hours; about 3 naps; 12-16 hours including naps.
• 7-9 months: awake 2.5-3.5 hours; 2-3 naps; 12-16 hours.
• 10-12 months: awake 3-4 hours; 2 naps; 12-16 hours.
• 12-24 months: awake 3-6 hours; 2 naps dropping to 1 (usually between 12 and 18 months); 11-14 hours.

Using the ranges

• Watch the baby more than the clock. Sleepy cues (yawning, rubbing eyes, staring off, fussing) matter more than a number.
• Short 30-45 minute naps are normal until about 4-6 months, because newborn sleep cycles are about 40-50 minutes and half of each is light, active sleep (grunting, twitching, brief cries). Pausing a minute before picking a baby up can let them drift back off.
• Mention loud nightly snoring, labored breathing or breathing pauses to the pediatrician (pauses of 20 seconds or more, color change or gasping: call right away).
