How many hours should a 24-day-old baby sleep per day normally?

A 24-day-old baby typically sleeps 18–22 hours a day, which is considered normal.

The neonatal period spans from birth to 28 days after birth. During this stage, normal sleep duration ranges from 18 to 22 hours. A 24-day-old infant falls within this neonatal period. Due to the immature development of the brain system, adequate sleep is essential for healthy growth and development. Generally, sleeping between 18 and 22 hours per day is normal. Because each baby has individual differences, sleep duration may vary slightly but usually remains within the normal range. As the baby grows and develops, total sleep time gradually decreases.

If a 24-day-old baby sleeps significantly more or less than usual and shows signs such as abnormally high excitability or lethargy, it is advisable to seek medical attention promptly for proper evaluation and diagnosis.
