Newborn Sleep: Understanding Your Baby's Sleep Patterns

when newborn sleep alot

Newborns generally sleep a lot—anywhere from 11 to 19 hours a day in their first year. However, this sleep is typically spread out in short bursts of 1-2 hours throughout the day and night, as newborns need to be fed and changed frequently. They also do not have an established sleep-wake rhythm and cannot differentiate between day and night. As a result, their sleep patterns tend to be erratic, and they may not sleep at what many consider to be the appropriate times. While most newborns follow their own sleep schedule, parents can help them develop a routine by exposing them to light and playing with them during the day, and providing a dim and quiet environment at night.

Newborns sleep a lot because they need to eat frequently

Newborns have different sleep patterns from adults. They sleep around the clock and do not have a sense of day and night. They sleep for 14 to 17 hours over a 24-hour period, with some newborns sleeping up to 18 to 19 hours a day. They wake up every couple of hours to feed and then go right back to sleep. This is because their tiny stomachs cannot hold enough breast milk or formula to keep them satisfied for long.

Breastfed babies need to feed more frequently, about every 2 to 4 hours, while bottle-fed babies can go a bit longer, about 3 to 4 hours. It is important to ensure that newborns are getting adequate nourishment, so they should be offered the breast, chest, or bottle every 1 to 2 hours, especially during the first two weeks. After this initial period, it is okay to let your baby sleep for longer periods at night if they are gaining weight well.

In the first few months, newborns cry a lot as it is their main way of communicating. They may be crying because they are hungry, need a diaper change, or simply want to be held and comforted. This can result in more frequent waking during the night. It is important to respond calmly and consistently to your baby's cries, as this is how they communicate their needs.

As newborns grow, they will start to develop a more consistent sleep schedule. They will begin to differentiate between day and night and will sleep longer stretches at night. This usually starts to happen around 3 to 6 months of age, when they may sleep for 5 to 6 hours at a stretch without feeding.

Newborns don't know the difference between day and night

Newborns follow their own schedules, and it may take a few weeks for their brains to distinguish between night and day. During this time, it's important to keep things quiet and calm during middle-of-the-night feedings and diaper changes. Keeping the lights low and avoiding playing or talking with your baby during this time can help send the message that nighttime is for sleeping.

To help your newborn establish a sense of day and night, you can differentiate between daytime and nighttime feeds. Feed your baby in a brightly lit, stimulating room during the day and in a dark room at night. While this may seem contradictory to the advice of creating a dark and quiet room for napping, it is specifically recommended for newborn babies during their first few weeks of life when their days and nights are mixed up.

Additionally, it is crucial to ensure your newborn doesn't nap too much during the day to help with day-night confusion. While good quality naps are important to prevent overtiredness, there can be too much of a good thing. If your newborn consistently sleeps for 3–4-hour stretches during the day, consider waking them up after a couple of hours to preserve longer stretches of sleep for the nighttime.

Remember, this phase of day-night confusion is normal and typically lasts for a few weeks to a couple of months. During this time, focus on creating a calm and relaxing bedtime routine to help your newborn learn the difference between day and night.

Safe sleep environments and room-sharing

Newborns tend to sleep a lot—anywhere from 11 to 19 hours per day, with some sleeping for up to 22 hours per day in the case of preemies. Their sleep patterns are often short and erratic, and they may sleep in small chunks or on an irregular schedule.

The safest sleep environment for a newborn is in their own crib, bassinet, or portable play yard in their parent's room for the first six months of their life. This arrangement, known as room-sharing without bed-sharing, allows the baby to be within arm's reach of the mother, enabling easy access for breastfeeding and comforting without sharing the same sleeping surface.

Room-sharing provides several benefits, including:

  • Reduced risk of Sudden Infant Death Syndrome (SIDS) and other sleep-related deaths: Research shows that room-sharing lowers the risk of SIDS and sleep-related infant deaths compared to bed-sharing or having the baby sleep in a separate room.
  • Ease of feeding, comforting, and monitoring: Having the baby nearby in the same room facilitates nighttime feedings, comforting, and monitoring, especially for breastfeeding mothers.
  • Development of a sleep routine: Placing the baby in their crib or bassinet at night helps them associate it with sleep, promoting the development of a sleep routine.

To create a safe sleep environment for room-sharing:

  • Ensure that the baby's crib, bassinet, or portable play yard meets current safety standards and is approved by the relevant consumer product safety organizations.
  • Avoid bed-sharing: Do not share an adult mattress, couch, or armchair with the baby, as it increases the risk of SIDS and sleep-related deaths due to suffocation or strangulation.
  • Keep the sleeping area clear: Remove pillows, blankets, and loose items from the baby's sleeping area to reduce the risk of suffocation and strangulation.
  • Place the baby on their back: Always put the baby to sleep on their back, rather than on their stomach or side.
  • Maintain a calm and quiet environment: During nighttime feedings and diaper changes, keep the lights low and avoid playing or talking with the baby to reinforce the association between nighttime and sleep.

By following these guidelines, parents can create a safe sleep environment for their newborns while also facilitating bonding and monitoring during the early months of their lives.

Newborn sleep patterns and cycles

Newborns sleep a lot—anywhere from 11 to 19 hours a day. Their sleep patterns tend to be short and erratic, and it’s uncommon for them to rest for more than a few hours at a time. They start their sleep cycle and spend most of their sleeping time in 'active' sleep.

Newborns don't yet have a sense of day and night. They sleep around the clock and wake often to eat, no matter the time of day. Newborns should get 14–17 hours of sleep over a 24-hour period, according to the National Sleep Foundation. Some newborns may sleep up to 18–19 hours a day. Newborns wake every couple of hours to eat. Breastfed babies feed often, about every 2–3 hours. Bottle-fed babies tend to feed less often, about every 3–4 hours.

In the first few months of life, babies' sleep is split nearly evenly between REM and NREM sleep stages. As a baby grows, they begin to spend less time in REM sleep. By adulthood, people experience REM for roughly 20% of each night's sleep, compared to the 50% of sleep newborns experience in REM.

Newborns and younger infants will fall asleep while breastfeeding. Having a routine at bedtime is a good idea. However, if a baby falls asleep in your arms, this may become a pattern. Your baby may then start to expect to be in your arms to fall asleep. After the newborn period, most experts recommend allowing your baby to become sleepy in your arms, then placing them in the bed while still awake. This way, your baby learns how to fall asleep on their own. Playing soft music while your baby is getting sleepy is also a good way to help create a bedtime routine.

When to be concerned about a newborn sleeping too much

It is normal for newborns to sleep a lot—anywhere between 11 to 19 hours per day. Newborns have their own schedule and sleep in short chunks of 1-2 hours at a time, waking up to feed and then going right back to sleep. In the first few weeks, it is important to wake your newborn to feed every 2-4 hours, depending on whether they are breastfed or formula-fed.

However, if your newborn is sleeping too much and missing meals, this could affect their weight gain and growth. If your newborn is regularly sleeping for more than 17 hours a day and is not eating at least eight times per day, you should consult a paediatrician. Other symptoms to look out for include extreme lethargy or fussiness when awake, signs of dehydration, and trouble waking up.

If your newborn is sleeping too much, there could be other reasons. They may be going through a growth spurt or developmental leap, or they may be unwell. In rare cases, excessive sleep in newborns can be a sign of a more serious medical condition, such as a breathing or heart disorder, or jaundice.

If you are concerned about your newborn's sleep habits, you can try keeping a sleep log to get a better understanding of their sleep patterns. You can also try strategies such as offering your baby a feed every 1-2 hours, making sure they are comfortable and not too hot or cold, and keeping the lights low and reducing stimulation during nighttime feeds. If you are still worried, consult a doctor or paediatrician.
