Sleep is the period when growth hormone is secreted, when learned things become permanent and when immunity is strengthened. It is a pillar of healthy growth that is just as important as nutrition.

Average Sleep Needs by Age (24 hours)

  • Newborn (0–3 months): 14–17 hours
  • Infant (4–12 months): 12–16 hours (including daytime naps)
  • 1–2 years: 11–14 hours
  • 3–5 years: 10–13 hours
  • 6–12 years: 9–12 hours
  • Adolescent: 8–10 hours

These ranges are averages; what matters is that the child is rested and cheerful during the day.

Telling Day from Night in Babies

Babies are born without knowing the difference between day and night; their biological clock matures during the first months. To support this process: let daytime naps happen in light and amid the sounds of everyday life; keep nighttime feedings in dim light, quiet and "boring." A simple, repeated evening routine (warm bath → feeding → dim room → lullaby) makes it easier for the baby to fall asleep. Don't forget the safe sleep rule: always on the back, on a flat and empty mattress.

Screens: Sleep's Greatest Enemy

The light from tablets, phones and television suppresses melatonin, the sleep hormone; it makes falling asleep harder and increases nighttime awakenings. Our recommendation: turn off all screens at least 1 hour before bedtime, keep no screens in the bedroom, and follow a consistent bedtime and wake-up schedule every day at the same time. Screens are not recommended at all under the age of 2.

When Does Sleeping Too Much Matter?

A temporary increase in sleep during growth spurts and after illness is normal. However, if excessive sleepiness during the day, difficulty waking in the morning and a marked decrease in the desire to play and eat persist as a departure from the usual routine, this should be evaluated (for causes such as infection, anemia or thyroid problems).
