What is the average sleep need for infants aged 0-2 months?

Infants aged 0-2 months have a significantly higher sleep requirement than older children and adults. During this stage of development, it is normal for them to need anywhere from 10.5 to 18 hours of sleep in a 24-hour period. This range encompasses both the various sleep patterns and the fact that their sleep is often broken up into multiple short periods throughout the day and night.

This sleep is crucial for their growth and development, as it supports their brain development, physical growth, and helps to establish healthy sleep-wake cycles as they mature.
