Ranges are general; every baby has individual needs.
What this means
Total sleep needs fall steadily as babies grow — from around 14–17 hours as a newborn down to about 11–14 hours for toddlers. The split also changes: newborns distribute sleep evenly across day and night, while by 6–12 months most sleep consolidates into a long night stretch plus 2–3 naps. These are typical ranges, not requirements; wake windows, temperament and development all shape any individual baby.
Recommendations
- Follow tiredness cues and wake windows rather than clock time alone — every baby varies.
- A consistent bedtime routine helps signal that sleep is coming.
- Expect sleep to shift around growth spurts and milestones — it's normal.
Watch out
- Ranges are averages, not quotas — a baby on the low or high end can be perfectly healthy.
- If sleep concerns are causing distress, talk to a pediatrician rather than self-diagnosing online.
