Newborns typically sleep for a total of 14 to 17 hours a day, spread across a 24-hour period. This sleep is not continuous but occurs in bouts of 1-3 hours due to their small stomachs, which require frequent feedings. However, sleep patterns can vary widely between individual newborns, and some may sleep as little as 11 hours or as much as 19 hours a day.
The Sleep Patterns of Newborns
Newborn babies have not yet developed a sense of night and day, which is partly why their sleep is not aligned to the usual day-night cycle. Their sleep is divided between REM (rapid eye movement) sleep, which is a light, active sleep where dreaming occurs, and non-REM sleep, which has three different stages and deepens progressively. Interestingly, newborns spend about half of their sleep time in REM sleep, compared to only about 25% for adults.
Their sleep cycle is typically about 50 minutes long, much shorter than that of adults, which is about 90 minutes long. This is why you might notice that your newborn seems to be waking up just as you’re about to catch some shut-eye yourself!
Understanding REM and Non-REM Sleep in Newborns
During REM sleep, you might observe your baby twitching, jerking, sucking, or even smiling. This type of sleep is crucial for the incredible development taking place in their brain. Non-REM sleep, on the other hand, progresses through stages of drowsiness to moderate then deep sleep. When babies enter the deepest stage of non-REM sleep, they are less likely to wake up.
While older children and adults cycle through REM and non-REM sleep several times during the night, newborns’ sleep cycles are shorter and more varied, and they might enter REM sleep almost immediately after falling asleep.
How Feeding Affects Newborn Sleep
Newborns need to be fed every two to three hours, which naturally disrupts their sleep. Breastfed babies may feed more often than formula-fed babies because breast milk is more quickly digested. It’s essential during these first few weeks to feed your baby on demand — this will support both their development and the establishment of your milk supply, if breastfeeding.
Some parents may notice that after the first few weeks, their baby may begin to sleep for slightly longer stretches at night. However, it’s important to keep in mind that ‘sleeping through the night’ during infancy is typically considered a stretch of about 5 hours.

Tips for Feeding and Sleep Routines
Setting up a bedtime routine early on can be beneficial, as it can help signal to your baby that it’s time to sleep. This might include a bath, a book, or a lullaby. During night feeds, you can keep the lights dim and the environment quiet to help your baby understand that nighttime is for sleeping.
Sleep Safety for Newborns
Beyond the number of hours, how babies are put to sleep is also crucial. To reduce the risk of Sudden Infant Death Syndrome (SIDS), it is recommended that babies be placed on their backs to sleep. A firm mattress in a safety-approved crib without pillows, soft toys, or loose bedding is the best sleeping environment for your little one.
Optimal Sleep Environment for Newborns
Ensuring a comfortable but safe sleep setting is paramount. Experts often suggest a relatively cool room temperature and recommend considering a wearable blanket or sleep sack as an alternative to loose blankets to keep the baby warm without the risks associated with loose fabrics. The room should be smoke-free, and while co-sleeping is common, it’s important to follow guidelines to prevent the risks of involuntary smothering or overheating.
The Importance of Parental Sleep and Support
It’s not just newborns who need to focus on sleep — parents do, too. The fragmented sleep schedule of a newborn can significantly disrupt a parent’s sleep cycle, leading to exhaustion and challenges in functioning during the day. It’s crucial for parents to try and rest when they can, possibly when the baby sleeps, and to seek support from family and friends. Taking turns on feeding duties (if possible, with expressed breast milk or formula), can also give each parent a slightly longer period of uninterrupted sleep.
Recognizing and Managing Sleep Deprivation in Parents
Learning the signs of sleep deprivation such as irritability, mood swings, memory issues, and an increase in mistakes or accidents can help parents realize when they need to take a step back and get some rest. It’s completely normal to ask for help, whether it’s from friends, family, or professional services.
Adapting to the Normal – Expect Changes in Sleep Patterns
Newborns will have varying sleep pattern changes as they grow within the first months of life. As their stomachs grow and they can hold more milk, they will start to sleep longer stretches. Typically, by the age of 3 months, many babies start to develop a more predictable pattern of sleep and may sleep for longer periods at night.
Anticipating Milestones and the Impact on Sleep
Remember, as newborns reach developmental milestones, their sleep patterns may change. Growth spurts, teething, and learning new skills may all impact how well a baby sleeps. Parents should expect and be prepared for variations and sometimes regressions in sleep patterns.
There will be good nights and challenging nights, but gradually, your baby’s sleep will become more predictable. Patience, flexibility, and understanding that all babies are unique and will reach sleeping through the night at their own pace, are key aspects of navigating newborn sleep.
Seeking Professional Advice When Needed
If your baby is having significant difficulties with sleeping, appears overly sleepy during the day, or if you as a parent are struggling to cope with the lack of sleep, it’s important to seek advice from your healthcare provider.
When to Consult a Healthcare Provider
Healthcare providers can help to assess whether there are any underlying health issues that need attention, provide guidance on sleep training methods if appropriate, and offer support for parents who are struggling with fatigue. Monitoring a newborn’s sleep patterns and addressing any concerns early on can help ensure healthy sleep habits and overall well-being for both the baby and the family.
Finishing Thoughts
In summary, newborn sleep is highly variable, but most newborns will sleep 14 to 17 hours in a 24-hour period in irregular bursts. Parents should provide a safe sleeping environment, be prepared for changes in sleep patterns as their baby grows, and take care of their own sleep needs as well. Above all, understanding that each baby is unique and may not adhere to any textbook pattern is crucial. Patience, flexibility, and the occasional professional consult can go a long way in navigating the wondrous, but often exhausting, new terrain of newborn sleep.
