Sleep is a crucial aspect of a baby's growth and development, and understanding the different stages of sleep is essential for parents. Newborns sleep up to 18 hours per day, with about 50% of their sleep time spent in REM sleep. Unlike adults, babies enter REM sleep immediately after falling asleep. During this stage, the brain is highly active, and it is believed that REM sleep is associated with memory formation and cognitive development in infants. This is what REM sleep looks like in newborns.
| Characteristics | Values |
|---|---|
| Time spent in REM sleep | Newborns spend about 50% of their sleep time in REM sleep, while adults only spend about 20% of each night's sleep in REM sleep. |
| Sleep cycles | Newborns may only experience two of the four sleep cycles: REM and non-REM (NREM). Infants 3 months and older can experience all four sleep cycles. |
| Eye movement | Rapid eye movement occurs during REM sleep, with the eyes moving back and forth or under closed eyelids. |
| Body movements | Twitching or jerking of the arms and legs can be observed during REM sleep. |
| Breathing | Irregular breathing, including periods of non-breathing for about 5-10 seconds, may occur during REM sleep. |
| Sounds | Brief grunting or crying may be heard during REM sleep. |
| Brain activity | REM sleep is associated with increased brain activity, memory formation, and cognitive development. It is also important for a baby's emotional development, as they may process and understand emotions during this stage. |

What You'll Learn
Newborns spend about 50% of their sleep time in REM sleep
REM sleep is one of the four cycles of sleep, with the other three being N1, N2, and N3, which are non-rapid eye movement (NREM) cycles. Newborns may only experience two of these four sleep cycles, REM and N3, with REM sleep being an active sleep stage. During this stage, a newborn's eyes can move underneath closed eyelids, and they may twitch or jerk their arms and legs. Their breathing can become irregular and faster, and they may make sucking or rooting motions.
REM sleep is important for a newborn's development, particularly for their brain and nervous system. It is during this stage that neural connections go into overdrive, with the brain actively processing information and consolidating memories. REM sleep is also associated with memory formation, cognitive development, and emotional processing in infants.
Parents can support their newborn's REM sleep by establishing a consistent bedtime routine, creating a soothing sleep environment, and encouraging regular naps. It is also important to respect their natural sleep cycles and not disturb them unnecessarily during active sleep. Additionally, putting babies to bed when they are drowsy but not asleep can help them fall asleep quickly and learn how to get themselves to sleep.

REM sleep is crucial for a newborn's brain development
Sleep is a crucial aspect of a newborn's growth and development. Newborns sleep up to 18 hours per day, with about 50% of their sleep time spent in REM sleep. This is significantly higher than the 20% of each night's sleep that adults spend in REM.
REM sleep is associated with dreaming, memory consolidation, emotional processing, and healthy brain development. During REM sleep, the brain is highly active, and neural connections go into overdrive. This increased brain activity is indicated by the twitching or jerking of the newborn's legs and arms, irregular breathing, and the movement of their eyes under closed eyelids.
The high ratio of REM sleep in newborns, which diminishes over time, suggests that REM sleep is essential for early brain development. This is supported by the fact that animals born with less developed brains, such as humans and puppies, spend more time in REM sleep during infancy than animals born with more developed brains, like horses and birds.
Research has shown that poor-quality sleep in hospitalized premature and term infants can have lasting effects on later cognitive functioning. In contrast, premature infants who had longer periods of sustained sleep and more time spent in REM sleep had better cognitive outcomes. These findings highlight the importance of interventions to improve sleep quality in neonatal intensive care units.

Newborns experience two sleep stages: REM and non-REM
Non-REM sleep is the initial stage of sleep and consists of four substages: NREM-1, NREM-2, NREM-3, and NREM-4. Each substage has its own unique characteristics and they are vital for physical restoration and growth. NREM-1 is the first stage of sleep, also known as transitional sleep, where babies may appear drowsy and may have their eyes open or closed. NREM-3 is the deepest cycle of sleep, and it is hard to wake a baby or adult during this stage.
Newborns have shorter sleep cycles than adults, with one full sleep cycle typically occurring in cycles of 20-40 minutes. As babies grow and sleep fewer hours, they spend less of their sleep time in the REM stage. By adulthood, people experience REM for about 20% of their nightly sleep. Establishing a consistent bedtime routine, creating a soothing sleep environment, and encouraging regular naps can all contribute to improving your baby's REM sleep.
It is important to note that babies can sense a parent's anxiety, which can disturb their sleep. Therefore, parents should remain calm and not overreact if their baby is making movements or noises during active sleep.

Newborns sleep up to 18 hours per day
Newborns typically sleep for 16 to 18 hours a day, with each nap lasting between one and four hours. This sleep is accumulated through a series of naps, as newborns don't have a sense of day and night, and they wake often to eat. Breastfed babies feed about every 2-3 hours, while bottle-fed babies tend to feed every 3-4 hours. Newborns who sleep for longer stretches should be awakened to feed until they show good weight gain, which usually happens within the first couple of weeks. After that, it's okay to let them sleep for longer periods at night.
Newborns spend about 50% of their sleep time in REM sleep, which is an active sleep stage. This is normal and will continue for the rest of their lives. During REM sleep, neural connections go into overdrive, and it is associated with memory formation and cognitive development in infants. REM sleep is also when babies may process and understand emotions, which is crucial for their emotional development.
During REM sleep, newborns may experience twitching or jerking of the legs, and their eyes may move under closed eyelids. They may also exhibit irregular breathing, grunting, or brief crying. These movements indicate increased brain activity during this phase.
As babies grow and sleep fewer hours, they spend less of their sleep time in the REM stage. By adulthood, people experience REM for about 20% of their nightly sleep.
To improve your newborn's REM sleep, you can establish a consistent bedtime routine, create a soothing sleep environment, and encourage regular naps. It is also important to ensure that all sleep surfaces and products you use for your baby are approved by the relevant safety authorities and meet federal safety standards.

Newborns may enter REM sleep immediately after falling asleep
Unlike adults, newborns enter REM sleep immediately after falling asleep. This is because newborns have shorter sleep cycles, with active sleep making up roughly 50% of each sleep cycle. One full sleep cycle in a newborn 0-3 or 4 months of age typically occurs in cycles of 20-40 minutes. Newborns sleep up to 18 hours per day, meaning they experience up to 9 hours of REM sleep daily.
During REM sleep, a baby's eyes move rapidly under closed eyelids, and their breathing becomes irregular and sometimes faster. Their muscle tone can fluctuate, and they may make sucking or rooting motions, as if they are feeding. REM sleep is an active sleep stage, similar to a waking stage. It is an important part of a baby's development, as neural connections go into overdrive. Babies spend much of their time in REM sleep to support their cognitive development.
Babies can experience irregular breathing followed by non-breathing for about 5-10 seconds. They may also grunt or cry briefly. During the REM cycle, babies' brains are actively processing information. Even if they're moving or making noises, they're probably still asleep, but it's easy to wake them.
Parents should respect these natural sleep cycles and not disturb the baby unnecessarily during active sleep. Since active sleep can sometimes precede feeding, parents should be prepared to feed their baby when they show signs of waking up, such as rooting or sucking motions. If your baby is in active sleep and making movements or noises, it's important to remain calm and not overreact. Babies can sense your anxiety, which can disturb their sleep.
