Newborn Sleep: What's Normal For Larger Babies?

Newborns sleep a lot—anywhere from 11 to 19 hours a day. This is completely normal, as they are growing and developing rapidly, and need adequate sleep to reach important milestones. Newborns also don't know the difference between day and night, and don't produce melatonin, the hormone that promotes sleep.

However, if a newborn is sleeping all day, it may be cause for concern. While newborns are not expected to have an established sleep-wake rhythm, they should still be waking up at least every three hours to feed. If they are sleeping through feedings, they may not be getting enough nourishment.

If you are concerned about your newborn's sleep patterns, consult a doctor.

Newborns sleep in short bursts, known as sleep cycles

It is normal for newborns to sleep all day. Newborns generally sleep between 12 and 17 hours in a 24-hour period, and this sleep is rarely continuous. Newborns sleep in short bursts, known as sleep cycles, which are usually around 20 to 50 minutes long. These 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 type of sleep is essential for brain development and processing the experiences of the day. Quiet sleep, on the other hand, is characterised by deep, restful sleep where the baby's body is still. This stage is crucial for physical growth and recovery.

Understanding these different sleep stages helps parents recognise their baby's needs and cues, ultimately leading to better management of sleep challenges. It is important to note that newborns need to eat frequently due to their tiny tummy size, so they may need to be woken up to feed even if they appear to be sleeping. This is especially important for breastfed newborns, as letting them sleep for too long can also cause a dip in the mother's milk supply.

As newborns grow, their sleep cycles gradually lengthen, and by the time they reach toddlerhood, they will have sleep cycles of about 90 minutes. By the age of six months, 90% of babies sleep through the night. However, it is important to remember that every baby is unique, and their sleep patterns and preferences will change as they grow.

Newborns don't know the difference between day and night

It's completely normal for larger newborns to sleep all day. In fact, newborns generally sleep for 12 to 17 hours within a 24-hour period, and this can even be up to 19 hours for some. Newborns don't know the difference between day and night and haven't yet established sleep-wake rhythms. They sleep in short bursts, usually around 20 to 50 minutes long, and wake frequently during the night to be fed or changed.

Newborns' sleep patterns can be confusing for new parents, especially when they seem to be the opposite of what we consider normal. This is known as day and night confusion or day and night reversal. It occurs because newborns are adjusting to life outside the womb and it can take time for them to settle into regular sleep patterns.

• Expose your baby to sunlight or natural light during the day. This will help them distinguish between light and dark and regulate their body clock.
• Encourage longer stretches of sleep at night. Limit daytime sleep to two hours at a time, or 90 to 105-minute naps. This will help your baby sleep longer stretches at night.
• Pay attention to your baby's sleep cues and feed them, expose them to sunlight, and put them back to sleep.
• Place your baby in their cot when they are tired but still awake. This will help them learn to self-settle.
• Establish a gentle, positive, and consistent routine, such as feed, play, sleep.
• Keep the nighttime environment dim and quiet, and expose them to light and gentle play during the day.
• Follow safe sleep practices, such as placing your baby on their back on a firm mattress with only a fitted sheet and no loose items in the crib.
• Keep things quiet and calm during middle-of-the-night feedings and diaper changes.
• Don't keep your baby awake during the day in the hopes that they will sleep better at night. Overly tired infants often have more trouble sleeping.

Newborns need to be woken up to feed

For the first two to three weeks, keep a close eye on the clock and wake your baby when it's time for them to eat. Breastfed babies shouldn't go longer than two to four hours without eating, while formula-fed babies can go three to four hours. In the case of breastfeeding, letting your newborn sleep for more than two to four hours can cause your milk supply to dip.

If your newborn seems to sleep all day and be awake all night, you should focus on correcting their day-night confusion. You can do this by exposing them to light and gently playing with them during the day, and providing a dim and quiet environment at night.

• Feed when your baby is in an active sleep period or REM sleep. You'll recognize this when your baby moves their arms and legs, changes their facial expressions, and flutters their eyelids.
• Slowly unswaddle them. If that doesn't work, try undressing them.
• Change their diaper while singing a song or stroking their hands and the soles of their feet.
• Hold your baby upright, which usually causes newborns to open their eyes.
• Dim the lights. If the room is too bright, your baby may be more comfortable keeping their eyes shut.
• Be social. Talk and sing to your baby, and make eye contact once you get their eyes open.
• Massage your baby's hands, feet, arms, back, and shoulders. Your touch can help wake your baby up.
• Place a cool (not cold) washcloth on their forehead.

Newborns sleep a lot because they are growing and developing

Newborns sleep a lot—anywhere from 11 to 19 hours a day—because they are growing and developing. In their first few months, newborns are still adjusting to life outside the womb and are not yet accustomed to the rhythms of a typical day and night. They also need to be fed regularly, so they usually sleep in short bursts, or sleep cycles, of 20 to 50 minutes.

Newborns go through intense periods of growth, or growth spurts, and they tend to sleep more during these times. During deep sleep, both infant bodies and brains grow. Sleep releases human growth hormone, and actual growth causes the body to use more energy, leading to increased food and sleep requirements.

Growth spurts tend to occur at specific times, including between two and three weeks old, around three months old, and about six months old. They can last anywhere from two days to a week, and during these periods, it's normal for a baby's sleep routine to change, especially at night. They may have trouble falling or staying asleep, but they will often make up for lost nighttime sleep with longer naps during the day.

In addition to growth spurts, there are other reasons why a newborn may sleep more than usual. They may be going through a developmental leap or experiencing a minor illness, such as a cold. In rare cases, excessive sleep could indicate a more serious medical condition or infection.

If you are concerned that your newborn is sleeping too much, look for other symptoms such as lethargy, difficulty eating, fussiness, or failure to gain weight. If you notice any of these signs, consult your paediatrician or healthcare provider.

Newborns sleep between 11 and 19 hours per day

Newborns sleep a lot—generally between 11 and 19 hours per day. This is because they are growing and developing rapidly, and need adequate sleep to ensure they can reach important milestones.

Newborns don't have a developed circadian rhythm, so they can't differentiate between day and night. They also don't produce melatonin, the hormone that promotes sleep. This means they don't know when it's time to sleep and when it's time to wake.

Newborns sleep in short bursts, known as sleep cycles, which are usually around 20 to 50 minutes long. They consist of active sleep and quiet sleep. During active sleep, a newborn may move, groan, open their eyes, cry out, or breathe noisily or irregularly. During quiet sleep, they will lie relatively still and their breathing will be more even.

It's important to note that newborns need to be fed regularly, so they usually sleep in short periods. They wake up frequently during the night, often because they need to be fed or changed.

As newborns grow into infants, they begin to develop a schedule and sleep longer at night. By the time they are 6 months old, 90% of babies sleep through the night.

While it's normal for newborns to sleep a lot, there are some instances where you may need to wake them for feedings. Newborns should feed every 2 to 3 hours. If they are sleeping longer than this, you may need to wake them to ensure they are getting enough nourishment.

If you are concerned about your newborn's sleep habits, it's a good idea to consult a pediatrician. They can help you determine if your baby is getting the right amount of sleep and offer advice on how to establish healthy sleep patterns.
