Newborns sleep differently from older babies, children, and adults. They sleep in short bursts, usually 20 to 50 minutes long, and wake frequently during the night. Newborn sleep cycles consist of active sleep and quiet sleep. During active sleep, newborns may move, groan, open their eyes, cry out, or breathe noisily or irregularly. This is a normal and essential part of a newborn's sleep cycle, reflecting their developing brain and nervous system.

Active sleep is a normal and essential part of a newborn's sleep cycle
A newborn's sleep cycle consists of active sleep and quiet sleep. During active sleep, a newborn may move, groan, open their eyes, cry out, or breathe noisily or irregularly. Their eyes move rapidly under closed eyelids, and their breathing becomes irregular and sometimes faster. Muscle tone can fluctuate, and they may make sucking or rooting motions, as if feeding.
Active sleep is similar to REM sleep for adults, but with one key difference: adults' skeletal muscles are paralysed during this stage, whereas babies' are not. Instead, babies move around, make noises, and sometimes open their eyes. Active sleep is crucial for a baby's brain development and nervous system development and maturation. It is believed that the brain works to organise the day's experiences and learning during this stage.
Newborns spend about half of their sleep time in active sleep, which is roughly 25 minutes of a 50-minute sleep cycle. As they get older, they will learn to settle themselves and fall back to sleep, a process known as self-settling.

Newborns sleep in short bursts, in cycles of 20-50 minutes
Newborns sleep for around 12 to 16 hours in a 24-hour period. They spend about half of their sleeping time in active sleep and half in quiet sleep. During active sleep, newborns may move, groan, open their eyes, cry out, or breathe noisily or irregularly. This can be mistaken for being awake, and parents may accidentally wake their baby by intervening during this time. During quiet sleep, newborns will lie relatively still and their breathing will be more even.
It is normal for newborns to wake between sleep cycles. As they get older, they will learn to settle themselves and fall back to sleep, known as self-settling. To help your newborn learn to sleep more at night, you can expose them to light and gently play with them during the day, and provide a dim and quiet environment at night. You can also establish a bedtime routine to help your baby calm down and know it's time for sleep.

During active sleep, newborns may move, groan, open their eyes, cry out or breathe irregularly
Active sleep is a normal and essential part of a newborn's sleep cycle. It is similar to REM sleep in adults, but with one key difference: newborns' skeletal muscles are not paralysed during this stage. Instead, they will move around, make noises like grunts and cries, and sometimes even open their eyes, all while they are actually asleep.
Newborns sleep in short bursts, with sleep cycles lasting around 20 to 50 minutes. They spend about half of their sleeping time in active sleep, and the other half in quiet sleep. During quiet sleep, they will lie relatively still and their breathing will be more even. It is normal for newborns to wake between sleep cycles, and as they get older, they will learn to settle themselves and fall back to sleep.
Newborns generally sleep 12 to 16 hours in a 24-hour period and do not know the difference between day and night. They do not have established sleep-wake rhythms, and will wake frequently during the night, often because they need to be fed or changed. From around two weeks to 3-4 months of age, newborns go through a stage of increased crying, which will be at its worst at 6-8 weeks.

Active sleep is similar to REM sleep in adults
Active sleep is a term used to describe the sleep behaviour of newborns. During active sleep, newborns may move, groan, open their eyes, cry out, or breathe noisily or irregularly. Newborns spend nearly half of their sleep time in active sleep, which is also known as REM sleep. REM stands for rapid eye movement, and it is characterised by quick eye movement, irregular breathing, elevated heart rate, and increased brain activity.
REM sleep is important for memory consolidation, emotional processing, brain development, and dreaming. During this stage, the brain repairs itself and processes emotional experiences, transferring short-term memories into long-term memories. Newborns spend eight hours in REM sleep each day, while by adulthood, this decreases to an average of two hours per night.
As newborns get older, their sleep cycles begin to shift into more adult-like sleep stages, and the amount of time spent in active sleep decreases. By the time a baby is 5 years old, they will be spending more time in the deeper stages of sleep, with the amount of deep sleep continuing to decrease as they get older.

Active sleep is crucial for a newborn's brain development
Active sleep is a normal and essential part of a newborn's sleep cycle. It is characterised by rapid eye movements, increased brain activity, and muscle tone changes. During active sleep, a newborn may move, groan, open their eyes, cry out, or breathe noisily or irregularly. This is different from quiet sleep, where they will lie relatively still and their breathing will be more even.
Newborns spend about half of their sleep time in active sleep, which is similar to REM sleep in adults. However, unlike adults, newborns' skeletal muscles are not paralysed during this stage, which is why they move around and make noises while sleeping.
To support your newborn's active sleep needs, it is important to create a safe and comfortable sleep environment. Newborns should sleep on their backs on a firm, flat surface, and their sleep area should be free of loose bedding, pillows, and soft toys to reduce the risk of SIDS (Sudden Infant Death Syndrome). It is also important to note that newborns do not have established sleep-wake rhythms and may wake frequently during the night for feeds or changes. By understanding your newborn's sleep patterns and providing a supportive environment, you can help them develop and grow in a healthy way.

Frequently asked questions
Active newborn sleep is a normal and essential part of a newborn's sleep cycle. It is similar to REM sleep in adults, but with a key difference: newborns are not paralysed during this stage and will move around, make noises, and sometimes open their eyes.
Newborns spend about half of their sleep time in active sleep, which is around 12-16 hours in a 24-hour period. Their sleep cycles are short, usually lasting 20-50 minutes, with active sleep making up roughly 50% of each cycle.
During active sleep, newborns may move, groan, open their eyes, cry out, or breathe noisily or irregularly. They may also make sucking or rooting motions as if they are feeding.
It is important to create positive sleep associations for your newborn. Some techniques, such as holding your baby until they fall asleep, can create a negative association, leading to them needing you to fall asleep. If you are concerned about any noises or movements your baby is making during active sleep, consult your pediatrician.
