3 Weeks Baby Not Sleeping At Night

Keep them awake a little longer during each waking period during the day. This will help increase the need for sleep later. Some sleep experts recommend playing with your baby for a few minutes after a feeding instead of letting your baby fall asleep.

Your newborn’s sleep patterns: At 3 weeks old, your newborn baby may begin to stay awake a bit longer during the day up to one hour or so but still will need to sleep about 16 hours in a 24-hour period . Unfortunately, he or she may also begin to become a bit fussier, in general.

Infants up to 3 months old should get 14 to 17 hours of sleep over a 24-hour period, says the National Sleep Foundation. Many will have settled into a daily sleep routine of two or three naps during the day, followed by a longer "sleeping through the night" stretch after a late-night feeding.

The exact age varies among children, depending on factors such as attending preschool, maturity, and nighttime sleep habits. At age three, almost all children still nap 2 at least once per day. Sixty percent of four-year-olds still nap.

Common Reasons for Babies to not Sleep: Parents missing tired signs. Babies give signals such as crying, grizzling and yawning when they’re tired and need to sleep. Missing a baby’s “sleep window” by keeping them up can mean babies take longer to settle.
