Understanding newborn sleep

In today’s world, parents are surrounded by messages telling them that babies should quickly learn to sleep independently, self-settle, and fit neatly into routines. It can feel like there is constant pressure to “fix” sleep as early as possible — and when that doesn’t happen, many parents are left wondering what they are doing wrong.

But the reality is, newborn sleep is not a problem to solve. It is a stage of development to understand.

One of the simplest ways to make sense of newborn behaviour is through evolution. Although we live in modern homes with monitors, white noise machines, and sleep schedules, our babies continue to be born with ancient instincts. In many ways, they are still “cave babies.”

Thousands of years ago, a baby separated from their caregiver would have been vulnerable. Staying close to a parent was essential for warmth, feeding, protection, and survival. Babies who cried to stay near their caregivers were biologically doing exactly what they were designed to do.

And those instincts have not disappeared just because society has changed.

Your newborn does not know they are safe, in a cosy home with a video monitor nearby. Their nervous system is wired to seek closeness. That is why many babies settle best when held, fed, rocked, or near their parents/caregivers. It is why they often wake and check for connection. It is why they crave contact naps and reassurance.

Responding consistently to those needs is an important part of building healthy attachment. When babies are comforted, fed, held, and reassured, they learn that they are safe, secure, and able to rely on their caregivers. Far from “spoiling” a baby, this responsive care helps lay the foundations for emotional security, confidence, and healthy relationships as they grow.

It is also completely normal for newborns to wake regularly to feed. Their stomachs are tiny, they digest milk quickly, and frequent feeding is biologically necessary for growth, development, and maintaining milk supply. Expecting long stretches of sleep from a newborn is often unrealistic because their bodies are designed to need regular nourishment, both day and night.

Frequent waking plays an important role in maintaining a lighter stage of sleep. Newborn sleep cycles are very different from an adult's, and these lighter periods of sleep help babies wake to feed, respond to their environment, and keep important functions such as breathing, temperature regulation, and heart rate working effectively as their systems continue to mature.

This is not “bad behaviour,” manipulation, or poor sleep habits. It is biology.

Yet modern parenting culture often expects babies to behave far beyond what is developmentally normal. Parents often feel their baby should self-settle early, sleep long stretches alone, or avoid “sleep associations.” When babies naturally struggle with these expectations, parents can feel like they are failing.

But we cannot expect a newborn with an immature nervous system to suddenly override thousands of years of biological programming.

Self-settling is not something babies simply decide to do because we encourage it enough. It is a developmental skill that grows gradually as the brain matures, emotional regulation develops, and babies begin to feel safe and secure enough to separate more confidently.

When we understand this, everything shifts.

Instead of seeing frequent waking as a problem, we begin to recognise it as normal infant behaviour. Instead of feeling guilty for rocking or feeding a baby to sleep, we understand that connection is often exactly what a newborn needs. Frequent night waking for feeds is not a sign that something is wrong — in the newborn stage, it is often a sign that your baby is doing exactly what they are biologically designed to do.

Instead of constantly chasing independence, we can focus on responsiveness, attachment, and realistic expectations.

This does not mean parents must never encourage healthy sleep habits or find ways to support rest for the whole family. But it does mean releasing the pressure to expect adult-like sleep from a tiny human who is still biologically programmed to stay close.

Because at the end of the day, your baby is not trying to make life difficult.

They are simply doing what humans have done since the beginning of time — staying close to the people who make them feel safe.

A child that feels safe, is a child that will thrive because they are full of confidence and love.
