Sleep is a common concern for parents of newborns. While it can be frustrating and exhausting, it's important to remember that your baby is not purposefully trying to keep you awake. There are many reasons why your 4-week-old might not be sleeping, including hunger, illness, discomfort due to conditions like colic or reflux, and confusion between day and night. Additionally, newborns often prefer to be held or sleep on their caregiver's chest for physical and emotional reasons, such as parent-child bonding and temperature regulation. This can make it challenging for them to fall asleep independently. It's also normal for newborns to have erratic sleep patterns, with frequent night awakenings and short naps, as their sleep cycles are still immature. Most babies don't start following a typical 24-hour cycle for sleeping and eating until they are 3-4 months old. While there are strategies to help you cope during this phase, it's essential to seek medical advice if you have concerns or suspect underlying issues.

What You'll Learn
Your baby is hungry or unwell
At four weeks old, a baby's sleep patterns are naturally erratic and unpredictable. They are still adjusting to life outside the womb and their sleep patterns are rapidly changing.
Your baby is hungry
Newborns don't eat much in one go, so they can wake up hungry and ready for more food. Hunger is a common reason for babies to wake during the night. Even if you have fed your baby recently, it is worth offering them more breast milk or formula to see if that is what they need. It is a good idea to schedule a feed just before nap time, but you should avoid feeding your baby to sleep if you can. Make sure your baby is getting enough sleep during the day to make up for any lost sleep at night, as it is harder for an overtired baby to settle.
Your baby is unwell
Your baby's digestive system is still maturing at four weeks, and they might experience discomfort due to conditions like colic or reflux. This can cause frequent night wakings and sleep disruptions. If your baby is unwell, contact your GP or paediatrician. Your baby might also be experiencing teething pain, which can start as early as three or four months.

They don't understand the time of day
It is normal for 4-week-old babies to have erratic sleep patterns, with frequent night awakenings, and late bedtimes. This is because they are still adjusting to life outside the womb, and their circadian rhythm has not yet fully matured.
At this stage, newborns typically sleep for about 15 to 16 hours per day, but this sleep is not continuous. Instead, it is broken up into several short naps and chunks of sleep. Most of their sleep time is spent in REM sleep, which is light sleep. This is why newborns often seem like they are stirring, twitching, sucking, or smiling in their sleep.
One reason why your 4-week-old baby may not be sleeping is that they don't understand the time of day. They may be on a day/night reversal schedule, sleeping well during the day but staying awake at night. Here are some tips to help your baby understand that day is for play and night is for rest:
- Keep your baby awake a little longer during each waking period during the day. This will help increase their need for sleep later.
- Avoid sleep-inducing activities during the day if possible. For example, keep them out of the car seat so that they can get some extra time awake.
- Get your baby outside and into the sun. Natural light helps reset their internal clock. If you can’t go outside, place their crib near a window that gets steady, bright light.
- At night, keep the lights low or turn them off near your baby’s sleeping area. Also, limit sound and movement while your baby is asleep.

They're getting used to life outside the womb
It is completely normal for a 4-week-old baby to wake up frequently in the middle of the night. At this age, your baby is still adjusting to life outside the womb, and their sleep patterns are naturally erratic and unpredictable. This is not a regression but a normal part of newborn development. Here are some reasons why your 4-week-old baby might be getting used to life outside the womb:
- Increased alertness: Your baby's senses are developing rapidly, and they are starting to notice their surroundings more. This increased alertness can disrupt their sleep patterns.
- Digestive system development: A baby's digestive system is still maturing at around 4 weeks, and they might experience discomfort due to conditions like colic or reflux. This discomfort can cause frequent night wakings and disrupted sleep.
- Day/night confusion: Newborns typically don't have a defined day or night schedule and sleep and wake at any time throughout a 24-hour period. This is because their circadian rhythm hasn't fully matured yet, and it's common for them not to have a clear night-day pattern.
- Need for comfort and bonding: Newborns often prefer to be held or sleep on their caregiver's chest due to physical and emotional reasons. Skin-to-skin contact promotes parent-child bonding and helps regulate the baby's heart rate, breathing, and body temperature.
- Immature sleep cycles: Most of a newborn's sleep time is spent in REM sleep, which is light sleep. They tend to stir, twitch, suck, or smile in their sleep, indicating immature sleep cycles.
- Health risks: The earlier a baby is born, the higher the health risks. Spending more time in the womb decreases health risks, and premature babies may face additional challenges adjusting to life outside the womb.

Their digestive system is still developing
It is normal for a 4-week-old baby to have erratic sleep patterns, including frequent night awakenings, late bedtimes, and unpredictable sleep schedules. This is because they are still adjusting to life outside the womb, and their sleep patterns are naturally erratic and unpredictable. This is not a regression but a normal part of newborn development.
One specific reason for this could be that their digestive system is still developing. At around four weeks, a baby's digestive system is still maturing, and they might experience discomfort due to conditions like colic or reflux. This discomfort can cause frequent night wakings and disruptions in their sleep. Newborns typically sleep for about 15 to 16 hours per day, but this sleep is not continuous; it is broken into several short naps and chunks of sleep, reflecting the immature sleep cycles of a newborn.
Most of their sleep time is spent in REM sleep, which is light sleep. Newborns are still getting used to life outside the womb and want to be near their caregivers. Holding your baby close promotes parent-child bonding and helps regulate their body temperature, heart rate, and breathing. Skin-to-skin contact, in particular, is beneficial for temperature regulation.
As your baby grows and develops, it is normal for them to prefer being held for sleep. However, if you are ready for your baby to sleep independently, you can start building sleep foundations and gradually transition them to sleeping in their own space. This is typically done when they are around 3-4 months old, as this is when babies start to follow a typical 24-hour cycle for sleeping and eating.
To help your baby sleep better, you can try keeping them awake a little longer during the day. This will increase their need for sleep later. Getting them outside in the sun or placing their crib near a window with steady, bright light can also help reset their internal clock. It is important to remember that your baby is not keeping you awake on purpose, and having empathy for their experience and patience with their development will make this phase easier to navigate.

They need help falling asleep
It is perfectly normal for a 4-week-old baby to need help falling asleep. They are still adjusting to life outside the womb and are getting used to their surroundings. Newborns need to be close to their primary caregivers to feel safe and comforted, and skin-to-skin contact promotes parent-child bonding and helps regulate the baby's heart rate, breathing, and body temperature.
If you are looking to give yourself a break from holding your baby to sleep, there are some things you can try. You can start by building a good sleep foundation, which you can build upon when your baby is older and able to learn independent sleep habits. You can try using swaddles, giving your baby time to "play" in their sleep space, and trying one crib nap per day. It is also beneficial to implement a consistent bedtime routine that includes lots of snuggles.
If you are looking for ways to help your baby fall asleep independently, you can try playing with them for a few minutes after feeding instead of letting them fall asleep. Getting them outside in the sun can help reset their internal clock, and placing their crib near a window that gets bright, steady light can also be beneficial. You can also try swaddling your baby at night, as this can help keep their arms and legs still so they don't move and wake themselves up.
Remember, it is normal for a 4-week-old baby to have erratic sleep patterns, and their sleep patterns will change as they grow and mature.

Frequently asked questions
At 4 weeks old, your baby is still adjusting to life outside the womb, and their sleep patterns are naturally erratic and unpredictable. This includes a common phenomenon known as day/night confusion and a tendency for newborns to have later bedtimes.
There are several strategies that can help your baby sleep. These include:
- Keeping them awake a little longer during the day to increase their need for sleep later.
- Getting them outside in the sun, as natural light helps reset their internal clock.
- Keeping it bright and noisy during the day and dark and quiet at night to help them distinguish between day and night.
- Swaddling them at night to keep their arms and legs still so they don't move and wake themselves up.
It is common for young babies to prefer sleeping on their caregiver's chest for physical and emotional reasons. Holding your baby close promotes parent-child bonding and helps them get used to your smell, touch, and voice. It also helps with temperature and breathing regulation, as newborns are unable to regulate their body temperature.
According to pediatric research, there is no evidence to support the existence of a 4-week sleep regression. The first significant sleep regression typically occurs around 4 months of age, when the baby starts to wake up to the world around them.
