The first week of a newborn’s life is filled with significant changes and developments. During this period, sleep is one of the most important aspects of their growth and overall health. New parents often wonder how much sleep their newborns need, as sleep patterns in infants differ greatly from those of older children or adults.
In this article, we will explore how much sleep a 1-week-old baby typically needs, the factors that affect their sleep, how to support healthy sleep habits, and what to expect in terms of sleep-wake cycles at this early stage of life.
The Sleep Needs of a 1-Week-Old Baby
Average Sleep Duration for Newborns
At 1 week old, most newborns sleep between 16 to 20 hours a day. This amount of sleep is crucial for their growth, development, and overall health. Unlike adults or older children, newborns do not follow a day-night sleep schedule. Instead, their sleep is spread out in shorter bursts throughout the day and night.
Newborns typically sleep in periods of 2 to 4 hours at a time. These short sleep cycles are due to their need to feed frequently, as their tiny stomachs can only hold small amounts of milk. After feeding, babies often fall back asleep, continuing their sleep-wake cycle.
Sleep in Relation to Feeding
One of the key factors determining how much a 1-week-old baby sleeps is their need to feed. Newborns need to eat every 2 to 3 hours, which means their sleep is frequently interrupted by hunger. Breastfed babies may wake up more frequently to nurse, while formula-fed babies may sleep slightly longer between feedings due to the slower digestion of formula.
Parents should expect their 1-week-old baby to wake up often to feed, which directly affects their sleep schedule. During this period, it is normal for babies to wake up regularly and sleep in short intervals.
Factors That Affect a 1-Week-Old Baby’s Sleep
Hunger and Feeding Patterns
As mentioned, hunger plays a significant role in determining a newborn’s sleep patterns. Since newborns need to eat frequently, hunger is one of the most common reasons why they wake up. A 1-week-old baby’s small stomach means that they cannot go for long periods without feeding. This is a normal and healthy behavior, and parents should be prepared for frequent nighttime wakings during this stage.
Day and Night Confusion
One of the challenges that parents may face with a 1-week-old baby is day and night confusion. At this age, newborns do not yet have a circadian rhythm, which is the internal body clock that helps regulate sleep and wakefulness in response to light and darkness. As a result, a 1-week-old baby may be more active at night and sleepier during the day.
It is common for newborns to have their sleep patterns reversed, sleeping more during the day and waking up frequently at night. Parents can help their baby gradually develop a more consistent sleep-wake cycle by keeping the environment dark and quiet at night and exposing the baby to natural light during the day.
Immature Sleep Cycles
Newborns have immature sleep cycles, which are much shorter than those of adults. At 1 week old, a baby’s sleep cycle typically lasts 50 to 60 minutes, and they spend a larger portion of their sleep in the REM (rapid eye movement) stage, which is lighter and more easily disrupted.
Since newborns spend more time in lighter sleep stages, they may wake up more frequently and need more sleep overall to compensate. This is a normal part of their development, and as they grow, their sleep cycles will lengthen, and they will spend more time in deeper stages of sleep.
The Startle Reflex (Moro Reflex)
Newborns, including 1-week-old babies, have a natural startle reflex, also known as the Moro reflex. This reflex can cause them to suddenly jerk or flail their arms and legs while sleeping, often startling themselves awake. The Moro reflex is a normal developmental response and typically disappears by the time the baby is 3 to 4 months old.
The startle reflex can disrupt a baby’s sleep, but swaddling the baby snugly in a blanket can help minimize its effects and allow the baby to sleep more soundly.
Supporting Healthy Sleep for a 1-Week-Old
Create a Calming Sleep Environment
While newborns do not yet follow a set sleep schedule, parents can help create a calming and comfortable environment that encourages healthy sleep. Here are a few tips for establishing a sleep-friendly environment for a 1-week-old:
Dim the lights: Keep the room dim or dark during nighttime feedings and diaper changes to help the baby learn to associate darkness with sleep.
Keep noise levels low: Reduce background noise and create a quiet atmosphere during sleep times to minimize disruptions.
Maintain a comfortable temperature: Ensure the room is kept at a comfortable temperature, typically between 68 to 72 degrees Fahrenheit (20 to 22 degrees Celsius), to promote restful sleep.
Swaddling for Comfort
Swaddling, which involves wrapping the baby snugly in a blanket, can help a 1-week-old feel secure and prevent their startle reflex from waking them up. Swaddling mimics the feeling of being in the womb, which can provide comfort and encourage longer periods of sleep.
However, it’s important to ensure that the baby is swaddled safely to prevent overheating or restricted movement. The baby’s hips and legs should have room to move freely, and the swaddle should not be too tight around the chest.
Encourage Safe Sleep Practices
Safe sleep practices are essential for reducing the risk of Sudden Infant Death Syndrome (SIDS). Here are some key recommendations for safe sleep:
Place the baby on their back to sleep: Always put your baby to sleep on their back on a firm, flat surface, such as a crib or bassinet, to reduce the risk of SIDS.
Use a firm mattress: Ensure that the baby’s sleep surface is firm and covered with a fitted sheet. Avoid using soft bedding, pillows, or stuffed animals in the crib.
Room-sharing, not bed-sharing: It’s recommended that babies sleep in the same room as their parents for the first 6 months but in a separate sleep space, such as a crib or bassinet.
Common Challenges with Newborn Sleep
Frequent Night Wakings
Frequent night wakings are one of the most challenging aspects of caring for a newborn. At 1 week old, it is normal for babies to wake up several times during the night to feed or be comforted. While this can be exhausting for parents, it is important to remember that frequent night wakings are part of a newborn’s normal development.
Parents can take turns feeding and comforting the baby during night wakings to ensure both caregivers get some rest. Over time, as the baby’s feeding patterns become more established, they will begin to sleep for longer stretches.
Difficulty Falling Asleep
Some 1-week-old babies may have difficulty falling asleep, especially if they are overstimulated or overtired. If a baby is having trouble settling down for sleep, parents can try using calming techniques such as:
Rocking or gentle swaying: Holding and gently rocking the baby can help soothe them and encourage sleep.
White noise: Playing soft white noise, such as a fan or white noise machine, can help block out background sounds and provide a calming effect.
Feeding before sleep: Feeding the baby right before sleep can help ensure that they are full and comfortable, making it easier for them to fall asleep.
What to Expect as the Baby Grows
Changes in Sleep Patterns
As the baby grows, their sleep patterns will gradually begin to change. By the time the baby is 2 to 3 months old, they will start to sleep for longer stretches at night and require fewer feedings. Their sleep cycles will also lengthen, and they will spend more time in deeper stages of sleep.
At this stage, parents can begin to establish a more structured sleep routine, such as a bedtime routine that includes calming activities like a warm bath, gentle rocking, or soft lullabies.
Developing a Sleep Schedule
By 3 to 4 months of age, many babies start to develop a more consistent sleep schedule, with longer periods of sleep at night and shorter naps during the day. Parents can help encourage healthy sleep habits by:
Setting a regular bedtime: Aim to put the baby to bed at the same time each night to help establish a routine.
Creating a calming bedtime routine: Establish a bedtime routine that signals to the baby that it’s time to sleep.
Exposing the baby to natural light during the day: This can help the baby gradually learn to differentiate between day and night, which is important for developing a healthy sleep-wake cycle.

Conclusion
A 1-week-old baby typically sleeps between 16 to 20 hours a day, broken up into shorter periods of sleep throughout the day and night. During this stage, frequent night wakings for feeding are normal, and parents should focus on creating a calming, safe sleep environment for their baby.
While sleep patterns in newborns are unpredictable, understanding the factors that affect a 1-week-old’s sleep and supporting healthy sleep habits can help both the baby and parents adjust to this new phase. As the baby grows and develops, their sleep patterns will gradually become more structured, leading to longer periods of rest and more consistency in their sleep-wake cycle.
