Sleep is essential for newborns, who spend more time asleep than awake. Newborns sleep around 14 to 17 hours over a 24-hour period, with some sleeping up to 18 or even 19 hours a day. Their sleep is typically divided into short segments of 1 to 2 hours at a time, and they wake up frequently to feed. Establishing a bedtime routine and creating a safe sleep environment are crucial for newborn sleep. Additionally, recognizing sleep readiness signs and teaching self-soothing techniques are important steps in promoting healthy sleep habits. Understanding the significance of sleep in newborn development, particularly for brain development, can help parents prioritize their baby's rest.
| Characteristics | Values |
|---|---|
| Amount of sleep | 14-17 hours of sleep over a 24-hour period, with some newborns sleeping up to 18-19 hours a day |
| Sleep cycle | Babies spend about half of their sleep in REM sleep, which is when dreams occur and the eyes move rapidly |
| Sleep patterns | Newborns don't initially have a sense of day and night, and it may take a few weeks for them to differentiate between the two |
| Feeding | Newborns wake up every few hours to feed, with breastfed babies feeding more frequently (every 2-3 hours) than bottle-fed babies (every 3-4 hours) |

Sleep patterns and cycles
The sleep cycle of a newborn is quite different from that of an adult. Newborns sleep for up to 18 hours a day, but in very short segments of about 1 to 2 hours at a time. They wake up frequently to feed, as their tiny stomachs cannot hold enough breast milk or formula to keep them satisfied for long.
Newborns do not have a sense of day and night, and it may take a few weeks for their brains to differentiate between the two. During this time, it is important to keep things quiet and calm during middle-of-the-night feedings and diaper changes, and to keep the lights low. This helps to establish the idea that nighttime is for sleeping.
Newborns spend roughly 50% of their time asleep in REM sleep, which is a light sleep when dreams occur and the eyes move rapidly. They spend the other half in non-REM sleep, which has four stages:
- Drowsiness: eyes droop, may open and close, dozing.
- Light sleep: the baby moves and may startle or jump with sounds.
- Deep sleep: the baby is quiet and does not move.
- Very deep sleep: the baby is quiet and does not move.
These cycles may occur several times during sleep, and babies may awaken as they pass from deep sleep to light sleep, and may have difficulty falling back asleep in the first few months.
It is important to note that not all babies know how to put themselves to sleep. Parents can help their babies fall asleep by recognizing signs of sleep readiness, establishing a bedtime routine, and providing a safe and comfortable environment.

Sleep environment
Sleep is essential for newborns, who sleep for around 14 to 18 hours a day. However, they wake up every few hours to feed, and their sleep patterns do not initially differentiate between day and night.
Creating a safe sleep environment for your newborn is crucial. Here are some key considerations and recommendations for establishing a secure and soothing sleep space:
Room and Sleep Surface:
- For the first six months, or ideally, the first year, the American Academy of Pediatrics (AAP) recommends room-sharing without bed-sharing. Place your baby's crib, portable crib, play yard, or bassinet in your bedroom, ensuring it meets safety standards.
- Make sure all sleep surfaces and products are specifically designed for sleeping babies and approved by the U.S. Consumer Product Safety Commission (CPSC). Avoid sitting devices, feeding pillows, infant loungers, and products claiming to reduce the risk of SIDS without approval.
- The crib or bassinet should be free of hazards like cords, ties, ribbons, or sharp objects. Keep hanging items like mobiles or pictures out of the baby's reach.
- The crib or bassinet mattress should be firm, covered with a fitted sheet, and free of soft bedding, pillows, or blankets that could pose a suffocation risk.
Sleep Position:
- Always place your baby on their back to sleep, as recommended by experts to reduce the risk of Sudden Infant Death Syndrome (SIDS). Side or stomach sleeping increases the risk of SIDS.
- Avoid using wedges, sleep positioners, or monitors that claim to lower the risk of SIDS, as there are no known products that can do this.
- Do not use weighted blankets, sleepers, or swaddles around your baby. Swaddling with a light blanket is generally considered safe until the baby starts trying to roll over or when they are 3 to 4 months old. Consult your doctor for proper swaddling techniques.
Temperature and Clothing:
- Ensure the room temperature is comfortable, as being too hot or too cold can disturb the baby's sleep.
- Dress the baby appropriately for the temperature, avoiding over-bundling. The baby should not feel hot to the touch.
Noise and Light:
- Keep the sleep environment calm and quiet, especially during middle-of-the-night feedings and diaper changes.
- Avoid stimulating activities or noise close to bedtime.
- Keep the lights low during nighttime routines to reinforce the difference between night and day.
Routine:
- Establish a bedtime routine that includes soothing activities like bathing, reading, and singing.
- Incorporate soft music to help establish a bedtime routine and signal sleep time.
- Be consistent with your routine, and your baby will soon associate these steps with sleeping.
Remember, the sleep environment should be safe, comfortable, and conducive to your newborn's sleep needs, allowing them to get the rest necessary for their development.

Sleep and brain development
Sleep is one of the primary activities of the brain during early development and plays a critical role in healthy cognitive and psychosocial development in early life. The early years of life are characterized by dramatic developmental changes, and sleep is just as important as proper nutrition in supporting a baby's brain development.
Newborns spend a large proportion of their time asleep, with sleep accounting for 50% of their time in the first few months of life. From birth to age 2, children spend more time asleep than awake. The amount of sleep needed decreases as children get older, with newborns requiring 16 to 17 hours of sleep in a 24-hour period, 14 to 15 hours at 16 weeks, and 13 to 14 hours by 6 months of age.
During sleep, an essential layer of fat called myelin forms around nerve fibers, and connections between the left and right hemispheres of the brain are strengthened. More than 1,000,000 neural connections are formed per second during the first three years of life. Sleep also plays a role in memory consolidation and emotional regulation. A well-rested baby will generally be more agreeable, eat better, and be easier to soothe.
Studies have found that inadequate sleep in children can lead to cognitive issues, developmental delays, and difficulties with concentration, impulse control, and learning. A Canadian study of toddlers found that those who got the most sleep were better at functioning and skills such as paying attention, setting goals, and staying on task. Additionally, children who do not get enough sleep are at a higher risk of obesity, as sleep deprivation can disrupt the hormone that signals when it is time to stop eating.

Sleep and physical development
Sleep is essential for newborns, who sleep for the majority of a 24-hour day. They sleep in short bouts, waking every few hours to feed. Newborns do not yet have a sense of day and night, and it may take a few weeks for their brains to differentiate between the two.
Sleep is as crucial as proper nutrition in supporting a baby's brain development. It also plays a vital role in physical growth. During sleep, the muscles receive an increased blood supply, energy is restored, and tissue growth and repair take place. An essential layer of fat called myelin forms around nerve fibres during sleep, and connections between the left and right hemispheres of children's brains are strengthened. These developments help brain functions mature and influence critical abilities such as language, attention, and impulse control.
Research has found that babies who sleep well through the night may develop better learning skills as toddlers. A Canadian study of toddlers found that those who got the most sleep were better at functioning and skills such as the ability to pay attention, set goals, and stay on task.
Sleep also helps babies to feel secure, which is important for their physical development as they are better able to handle separations, especially at night. Cuddling and comforting a baby during the day can help them feel more secure.
Babies who are held or carried during the day tend to have less colic and fussiness, which can also aid their physical development.
Sleep problems may occur with illness. If a baby begins having trouble sleeping or staying asleep, it is important to talk to their healthcare provider, especially if this is a new pattern.

Sleep and mental development
Sleep is crucial for newborns, and they need a lot more of it than adults. From birth to age 2, children spend more time asleep than awake, with newborns requiring 14 to 18 hours of sleep per day.
Sleep is as crucial as proper nutrition in supporting your baby's brain development. An essential layer of fat called myelin forms around nerve fibres during sleep, and research shows that connections between the left and right hemispheres of children's brains are strengthened during sleep. These developments help brain functions mature and influence critical abilities such as language, attention, and impulse control.
Studies have shown that sleep plays a large role in memory, generalization, and word learning, and children who don't get enough sleep have poorer cognitive performance. Sleep also consolidates memories and improves vocabulary, attention, and mood.
A Canadian study of toddlers found that those who got the most sleep were better at functioning and skills, including the ability to pay attention, set goals, and stay on task. Another study found that children who get insufficient sleep in their toddler and preschool years have a higher risk of poor emotional control, peer relationships, and attention at 7 years old.
It's important to note that every child is unique, and their sleep patterns and needs will vary. Breastfed newborns, for example, wake up more frequently than formula-fed babies. As babies grow, their sleep needs change, and they may start sleeping for longer stretches at night.
Understanding your newborn's sleep patterns and needs is essential for promoting healthy mental and overall development.
