Discover the Sleep Cycle of Babies

Sleep is a crucial process that helps babies, and adults catch up on their sleep. Baby’s sleep cycle differs from adults, who typically go through four different phases during the night. In this post, we will describe the sleep cycle of babies and how and how it differs from adults.

The Sleep Cycle of Babies

Babies have different stages and depths of sleep. The first stages of sleep are called quiet sleep, active sleep, and REM sleep. The first three stages are all characterized by very little movement, with the exception of rapid eye movement (REM) sleep. During quiet sleep, a baby’s breathing is slow and deep. 

Active sleep is characterized by frequent movements and breathing. REM sleep is characterized by very frequent, rhythmic eye movements and is associated with rapid breathing and a brief period of unconsciousness. In addition to these stages, babies also have two intermediate stages between quiet and active sleep: drowsy sleep and transitional sleep.

Babies tend to be more alert and wake up during the night. At around 4 months, they will start to have longer naps during the day. This is a normal phase, and it means that you should be more active with your baby during the day. The third stage of sleep in babies is referred to as deep sleep, and this is when babies dream. It’s the best time for them to learn and develop. You can also expect them to gain weight. As your baby starts sleeping through the night, you’ll know that she is ready for the fourth stage of sleep.

During the first few months of life, a baby’s sleep is characterized by frequent arousals, crying, and feeding. The transition to more consolidated sleep occurs over time. During the second year of life, children begin to move from primarily rapid eye movement (REM) sleep to slow-wave sleep (SWS), which is characterized by longer periods of REM sleep. Many parents are surprised when they discover that their infants and young children rarely have an uninterrupted night’s sleep. This is true for babies who are awake and active.

The Difference Between baby's sleep and adult sleep

According to many experts, baby sleep is different from adult sleep. Baby’s sleep is often interrupted and irregular, while adult sleep is typically deep and uninterrupted. This difference can have a big impact on how babies and adults feel during the day and at night. 

Most adults sleep 7-8 hours’ per nightwhile infants typically sleep 16-18 hours nightly. Sleep patterns are highly influenced by circadian rhythms. These rhythms help the body regulate and maintain optimal health. Sleep is a critical component of healthy development that occurs during infancy and toddlerhood. Without proper sleep, infants may not be able to develop properly. 

Newborn babies wake up throughout the night because they have not fully developed a strong circadian rhythm that makes children and adults tired at night instead of during the day. Babies sleep in a “fuzzy” state because they still cannot differentiate between light and dark. This is why they cry while they are awake, but not asleep. Babies who have been awake for longer than 3 hours have a greater tendency to wake up in the middle of the night. 

Babies begin to develop an “adult” sleep cycle between three months and one year of age. Babies begin to sleep for longer periods during the night and shorter periods during the day. Not all babies conform to the same sleep schedule at the same age. Sleep patterns of babies depend on their stage of development, the environment they live in, and their overall health. Sleep-related behaviors vary between infants and toddlers. Babies begin to walk at 10 or 11 months of age. Babies sleep in different ways at each age and are affected differently by different factors.


The amount of sleep needed by infants varies from baby to baby. Most babies require 16 to 20 hours of sleep each day.

The best way to help your baby sleep is to put them down to sleep in their crib. Make sure they are comfortable and that they have their own bed.


It is important to know the sleep cycle of babies in order to help them fall asleep at the right time and maintain a healthy sleep schedule. If you are not sure how your baby is sleeping, it is best to consult with a pediatrician or sleep consultant.
