Many parents find themselves surprised when their newborn, who once slept soundly, becomes a light sleeper, waking at the slightest noise. However, it is a common misconception that some babies are simply light sleepers while others are heavy sleepers. In reality, all babies, like all adults, are both light and heavy sleepers, moving in and out of light and deep sleep several times a night. The difference lies in the amount of time spent in each stage of sleep and the ability to fall back asleep independently.

What You'll Learn

Sleep cycles
Newborns spend more time in light sleep than adults. They have shorter sleep cycles than adults. Typically, newborns take about 45 minutes to complete a cycle, while adults take nearly double that time. This means that newborns spend twice as much time in the light sleep stage than adults, making them more prone to waking up.
As newborns grow and develop, their sleep habits change. Initially, they cannot distinguish between day and night, but as they get older, they start to understand that nights are for sleeping and days are for play. Newborns also become more curious about the world, and their increased sensory perception can make them more easily distracted and likely to respond to sights and sounds.
While you cannot control a newborn's sleep cycle or prevent them from waking up, you can teach them to fall back asleep independently. This skill will benefit both the newborn and the entire family, leading to full nights of deep, uninterrupted sleep for everyone.

External distractions
Newborns are light sleepers because they are curious about the world and don't want to sleep through it. As they grow older, they start recognizing sights and sounds more clearly and are more likely to respond to them.
Babies have shorter sleep cycles than adults and spend twice as much time in light sleep stages than adults. This means that they are more likely to be woken up by external distractions such as noise or movement. For example, an ambulance passing by the house, neighborhood kids shouting, or a parent moving around can all be potential distractions that wake a baby up.
To reduce the impact of external distractions, some parents use tools such as blackout curtains and white noise machines to create a more consistent and soothing sleep environment for their babies. Others choose to go in the opposite direction, letting their babies get used to the house noises and sleeping in a cot or a grobag.

Fear of missing out
It's natural for newborns to be light sleepers. As they grow, their senses develop, and they become more curious about the world around them. As they start to recognise sights and sounds more clearly, they also become more responsive to them. This newfound curiosity may cause them to become restless, as they don't want to miss out on anything.
While you can't change the world around your baby, you can take steps to minimise distractions during nap time. Here are some strategies to help your newborn sleep better:
- Use blackout curtains to make the room darker and minimise visual distractions.
- Create a boring and unengaging environment during sleep times.
- Ensure they get plenty of sunlight in the afternoon to help regulate their sleep-wake cycle.
- Use a white noise machine to drown out external noises.
- Teach your baby to fall asleep independently. This is a valuable skill that will benefit both your baby's sleep and your own.
It's a Phase
Remember, your baby's sleep habits will change over time. Many newborns are light sleepers, but they will gradually outgrow this phase as they learn to self-soothe and regulate their sleep.
It's important to note that all babies, like adults, experience both light and deep sleep. The difference is that babies spend more time in light sleep, which is the stage most prone to interruptions from external stimuli.
By creating a calm and soothing environment and teaching independent sleep skills, you can help your baby get the rest they need.

Day-night confusion
When babies are first born, they can't tell the difference between day and night. As they get older, they start to figure out that nights are for sleeping and days are for play. However, some babies get confused and mix it up, trying to stay awake all night and sleep through the day. This is known as day-night confusion.
If your newborn is experiencing day-night confusion, there are a few things you can do to help them establish a more regular sleep pattern. Firstly, make sure they get plenty of sunlight in the afternoon. This will help them associate daylight with being awake and active. Secondly, make sure their nighttime environment is as dark, quiet, and unstimulating as possible. This includes their room as well as the surroundings when they wake up during the night. Avoid turning on bright lights or making loud noises, and keep interactions brief and boring to encourage them to fall back asleep.
Another important aspect is teaching your baby to fall asleep independently. This doesn't mean leaving them to cry, but rather providing a safe and comfortable space for them to learn to self-soothe. You can do this by ensuring they don't become dependent on external props, such as rocking or feeding, to fall asleep. Instead, create a consistent bedtime routine that helps signal to your baby that it's time to sleep. Over time, they will learn to associate these cues with sleep and develop the skills to fall asleep on their own.
Additionally, you can try using tools like blackout curtains and white noise machines to create a more sleep-conducive environment. These tools can help block out external distractions and provide a sense of calm for your baby. Remember, it's important to be consistent with these strategies and give your baby time to adjust. Every baby is unique, and it may take some trial and error to find what works best for your little one.
Remember, it's normal for newborns to be light sleepers, and their sleep patterns will change as they grow. Be patient, consistent, and responsive to your baby's needs, and they will gradually develop healthier sleep habits over time.

Self-soothing
Newborns are not typically capable of self-soothing. In the early days, they are unable to voluntarily control their hands or movements enough to self-soothe and rely on their parents or caregivers to help settle them to sleep. This could be by rocking, patting, or feeding them. However, this does not mean that parents are "spoiling" their baby by helping them fall asleep.
As babies grow older, they develop the capacity to self-soothe. Most babies learn to self-soothe at around 4 to 5 months old. At this age, they will develop the ability to self-regulate and calm themselves when they wake up during the night. They will also be able to self-soothe when they come into the light sleep state, which means that they are linking their sleep cycles and are more likely to settle back to sleep.
Parents can encourage their baby to self-soothe by establishing a sleep routine and healthy sleep habits from birth. This includes putting the baby to bed at the same time each night in a quiet, dark room, and establishing a bedtime routine, such as a bath or a bedtime story. It is also important to ensure the baby feels safe and secure, and to limit daytime naps to no more than 3 hours.
It is a common misconception that "self-soothing" means letting a baby "cry it out". This is not true, and teaching a baby calming strategies gives them an important life skill.
