How Long Until Your Newborn Sleeps Through The Night?

when do newborns sleep through

Sleep is essential for both babies and parents, and it's natural for new parents to wonder when their baby will sleep through the night. Newborns typically sleep for two to four hours at a time, and they need to eat every few hours, so they won't sleep through the night initially. As they get older, babies can sleep for longer stretches, and by three to four months, they may sleep for six hours without feeding. By six months, many babies are developmentally capable of sleeping through the night, but some may still need night feeds. Establishing a bedtime routine and good sleep habits can help your baby sleep longer, but remember that every baby is unique, and it's essential to consult a healthcare professional if you have concerns.

Newborns sleep for 12-18 hours a day

Newborns sleep for around 12 to 18 hours a day. However, this sleep is not continuous and is spread across several sleep cycles throughout the day and night. Newborns do not have established sleep-wake rhythms and do not know the difference between day and night. They wake up frequently to feed as they have small stomachs and need to be fed regularly.

During the first few weeks, newborns sleep in short, random bursts of around 2 to 4 hours at a time. The total daily sleep of a newborn can range from 8 to 20 hours, with some sleeping for only 10 hours and others sleeping for up to 18 or even 20 hours. This variation is normal, and individual sleep needs may differ.

Newborns follow their own sleep schedules, and it may take a few weeks for them to settle into a routine. During this time, it is important to focus on meeting their feeding needs rather than establishing a strict sleeping routine. It is recommended to keep things quiet and calm during nighttime feedings and diaper changes, maintaining low lighting, and allowing the baby to fall asleep in their crib to associate it with sleep.

While it is normal for newborns to wake up frequently, if you are concerned about their crying or sleep patterns, it is best to consult a healthcare professional, such as your baby's GP or health visitor. They can provide personalised advice and address any specific concerns or questions you may have about your baby's sleep patterns.

Additionally, it is important to prioritise safe sleeping practices for your newborn. Ensure that all sleep surfaces and products are approved by the relevant safety organisations and meet federal safety standards. Avoid using weighted blankets, sleepers, or swaddles, and be cautious of advice or products that claim to help your baby sleep longer or deeper, as this can be dangerous and affect their ability to wake up when needed.

They wake often to feed

Newborns have tiny stomachs that can't hold enough breast milk or formula to keep them full for long, so they need to wake up often to feed. They sleep for around 8–9 hours during the day and 8 hours at night, but they usually wake up at least every 3 hours to feed. Breastfed babies need to feed more frequently, about every 2–3 hours, while bottle-fed babies can go a bit longer, typically 3–4 hours between feedings.

During the first two months of a baby's life, sleep comes in short bursts of 30 minutes to three hours at a time. They will wake up for about two hours before going back to sleep. These short bursts of sleep and wakefulness are a normal and important part of a baby's growth. It's important to feed newborns whenever they show hunger cues, such as rooting, sucking, or sticking out their tongue.

If your baby is younger than one month old, they may not wake up when they feel hungry. Babies younger than four weeks old should not go longer than 4–5 hours without food. To wake a baby up to eat, you can try gently brushing the side of their cheek or gently wiggling their toes or stroking the bottoms of their feet. It's important to consult a pediatrician or nursing expert for individual advice based on your baby's needs and development.

In addition to feeding, creating a calm and quiet environment during middle-of-the-night feedings and diaper changes can help your baby learn that nighttime is for sleeping. Keeping the lights low and avoiding playing or talking with your baby during these times can reinforce this association. Establishing a bedtime routine that includes feeding your baby at the start can also help them learn that nighttime is for sleeping and reduce their reliance on feeding to fall asleep.

They don't know the difference between day and night

Newborns typically sleep in short, random bursts, and they wake up frequently to feed. They don't have a sense of day and night yet, so they might sleep when they're supposed to be awake and stay awake all night. This is known as day-night confusion or day-night reversal.

Newborns are adjusting to life outside the womb, which was dark, noisy, and cushiony, with their mother's movements rocking them to sleep during the day. It takes time for their circadian rhythm, or their internal 24-hour rhythm, to develop. This usually starts to become regulated around 4 to 5 months, and by about 4 months, their day and night confusion will likely have passed.

To help your newborn learn the difference between day and night, you can establish a calm and relaxing bedtime routine that's slightly different from their daytime nap routine. For example, your bedtime routine could include a bath, dimming the lights, reducing noise, a feed, a massage, a diaper change, and a bedtime song. The routine should end with placing your baby in their bassinet for bedtime. This will signal to your baby that it's time to wind down and prepare for sleep.

It's also important to engage your baby in stimulating activities during the day, such as tummy time, gentle play, and interaction with family members. This will help promote alertness and make your baby more tired at night. Exposing your baby to natural light during the day and keeping the lights dim at night can also help regulate their circadian rhythm.

Additionally, you can try capping your newborn's naps to no more than two hours to encourage longer stretches of sleep at night. If your baby has been sleeping for 3 hours during the day, you can gently wake them for a feed to establish more feeds during the day than at night.

It's normal for newborns to wake up repeatedly in the night

It's completely normal for newborns to wake up repeatedly during the night. Newborns generally sleep for 12 to 18 hours in a 24-hour period, but this is usually spread across several sleep cycles, both during the day and at night. Newborns need to feed regularly, so they sleep in short bursts, usually around 2 to 4 hours at a time. They also have tiny tummies, so they need to feed often, no matter the time of day.

Newborns don't yet have a sense of day and night, and it may take a few weeks for their brains to develop this distinction. During this time, it's helpful 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 will help send the message that nighttime is for sleeping.

Each baby has a unique sleep pattern, and some may start to sleep through the night (for 5 to 8 hours) by 2 to 3 months of age, but this is not the case for all babies. It's important to remember that all babies are different, and the amount of sleep they need will vary. As your baby grows, they will need fewer night feeds and may be able to sleep for longer periods.

It's normal to feel exhausted and sleep-deprived as a new parent, and it can be helpful to nap during the day to maintain your energy levels. Remember that it takes time to establish a routine, and it's essential to be patient and follow your baby's lead.

Sleep training methods may help babies sleep for longer

Sleep training methods can be beneficial for babies and their caregivers. The goal of sleep training is to help babies sleep through the night without needing external help to fall back asleep. However, it's important to note that newborns have different sleep patterns and sleep training is not recommended for them. Newborns have underdeveloped circadian rhythms, which means they don't have a well-established day-night sleep cycle. Instead of formal sleep training, the focus should be on creating a safe, comfortable, and calm sleep environment to optimise sleep.

As babies grow older, their sleep patterns start to change, and they may begin to sleep for longer periods. Around the 3-month mark, some babies may start to sleep for 5-6 hours at a time, while others may not. This is also when they may be able to start gentle sleep training methods such as the "pick-up/put-down" method. With this approach, the baby is placed in their crib while drowsy but still awake. If they start to fuss, the parent waits a bit, then picks them up to console them before placing them back in the crib. This process is repeated until the baby falls asleep, gradually increasing the wait time before picking them up.

By 4 months, most babies can sleep for six hours between feeds overnight, and by 6 months, most can sleep through the night. This is typically when more structured sleep training methods can be introduced. One such method is the "Cry It Out" approach, also known as CIO or extinction. With this technique, parents follow a bedtime routine, give their baby a cuddle and a kiss goodnight, and then leave the room. If the baby cries, the parent does not respond, allowing the baby to self-soothe or tire themselves out. While this method can be effective and quick, some parents are uncomfortable with letting their baby cry without providing comfort.

It's important to remember that there is no one-size-fits-all approach to sleep training, and the best method depends on what works for the baby and their family. Some gentler methods that minimise crying may take longer but can still be beneficial for both babies and caregivers. Sleep training can lead to more restful sleep for babies, resulting in improved developmental and behavioural outcomes and a happier temperament. Additionally, well-rested parents can experience improved mental health and overall quality of life.

Frequently asked questions

Newborns generally sleep between 12 to 18 hours in a 24-hour period. However, this varies from baby to baby, with some sleeping for as little as 10 hours and others sleeping for up to 20 hours.

Newborns sleep in short bursts, known as sleep cycles, which are usually around 20 to 50 minutes long. They wake up frequently to feed, as they have tiny tummies.

There is no definitive answer to this question as every baby is different. Some newborns may start sleeping through the night (for 5-8 hours at a time) by 2-3 months of age, while others may take longer.
