How Smell Shapes Early Memory in Newborns

A newborn enters the world with senses that are still developing, but the sense of smell is surprisingly advanced from the very beginning. Long before babies learn to see clearly or recognise distant sounds, they rely on scent to feel secure, find comfort, and understand what is familiar. Smell is the first thing that helps them identify their caregiver, learn about routines, and make emotional memories that shape how they react to the world.

The mother's body, amniotic fluid, and hormones all emit subtle odours that fill the womb. These smells are the baby's first sensory experiences, and they start to build a memory bank even before birth. After delivery, when babies are placed close to their caregiver’s chest, they instantly recognise the familiar scent they have known for months. This recognition is a key part of bonding, trust, and emotional safety, highlighting how your presence influences their development.

How Smell Develops Before Birth

Smell is one of the earliest senses to mature in the womb. By the third trimester, babies are already able to recognise and respond to familiar scents within the amniotic fluid. Here’s how this early development shapes memory:

Your baby becomes familiar with the natural scent patterns of pregnancy, which later help them recognise their caregiver after birth.
Your baby responds to familiar smells in the womb, forming early sensory memories that bring comfort after delivery.
Your baby begins building neural pathways that help them associate scents with safety and familiarity.

How Newborns Recognise Their Caregiver Through Smell

The moment a newborn is placed on the chest, their sense of smell becomes their main guide. They turn towards the familiar scent they remember from the womb, helping them feel grounded and comforted. Recognising your scent can make your baby feel safe in a new environment, reinforcing their sense of security and your role in their comfort.

Your baby identifies you through your natural scent, which helps them feel safe in a completely new environment.
Your baby responds to familiar smells by relaxing, settling their breathing, and feeling more emotionally secure.
Your baby begins forming early memories by linking your scent with comfort and nourishment.

How Smell Shapes Emotional Bonding

Bonding is not just an emotional experience; it is also a sensory one. Smell plays a significant role in helping your baby connect with you in the first days and weeks after birth. Here’s how smell strengthens bonding:

Your baby learns to associate your scent with calmness, warmth, and feeding, which strengthens emotional closeness.
Your baby feels reassured when they sense your scent during feeding, holding, or cuddling.
Your baby learns to trust you early on because your scent always means safety when they are held.

How Smell Affects Early Feeding Behaviour

Newborns naturally use smell to find the breast when they are first feeding. Their sense of smell helps them find their way as they try to eat for the first time. Here's how smell helps with feeding:

Your baby moves towards the breast instinctively because the scent feels familiar and comforting.
Your baby uses smell to recognise the milk’s natural aroma, which helps them begin feeding more confidently.
Your baby associates feeding time with emotional comfort through repeated experiences of scent and warmth.

How Smell Helps Babies Form Early Memories

Newborns don't remember things the same way adults do. They depend a lot on sensory cues, especially smell. The first building block of early memory formation is scent. Here's how smell affects memory:

Repeated smells help your baby remember people, things, and routines, which makes them feel more settled.
Your baby begins to distinguish familiar environments from unfamiliar ones through the smells they experience daily.
Your baby feels calmer when familiar scents are present because these scents activate early memory patterns linked to comfort.

How Scent Provides Comfort During Stress or Discomfort

Newborns often feel overwhelmed by new experiences, such as hunger, cold, noise, or pain. Familiar smells help calm them and make them feel more emotionally stable. If your baby smells you, they may stop crying sooner. It can help you feel better knowing that you are there for them during stressful times.

Your baby may stop crying more quickly when they sense your scent, as it feels familiar and reassuring.
Your baby’s heart rate can steady when they encounter scents associated with security, such as your clothing or your natural scent.
Your baby relaxes more easily during sleep, feeding, or cuddling when familiar scents surround them.

How Babies Learn Social and Emotional Cues Through Smell

Smell not only supports bonding; it also helps babies understand social connections. Babies pick up subtle scent differences from caregivers, helping them build early social awareness. Here’s how scent shapes social learning:

Your baby begins to recognise the scents of close family members, which helps them understand who is familiar.
Your baby feels comfortable with certain people because their scent becomes part of their early memory network.
Your baby experiences emotional stability when people they trust hold them, supported by familiar scent cues.

Ways Parents Can Support Healthy Scent Memory Development

Supporting your baby’s sensory and emotional development through smell is natural and straightforward. You can intentionally use scent to enhance bonding by holding your baby close during feeding, soothing, or skin-to-skin time, which helps them recognise and remember your scent.

You can hold your baby close during feeding, soothing, or skin-to-skin time to help them recognise and remember your scent.
To support your baby's scent-based bonding, avoid strong perfumes or chemical fragrances, as these can interfere with your baby's ability to focus on natural, familiar scents and may cause discomfort.
You can keep a soft cloth or a piece of clothing near your baby that carries your natural scent to help them feel secure during naps.
You can respond gently and consistently to your baby’s needs, helping them build positive scent-linked memories.
You can use calm, predictable routines to help your baby associate certain scents with comfort, rest, and emotional safety.

The world of a newborn is based on smell. Smell helps babies understand comfort, safety, and connection by helping them remember things from when they were born. The warmth of your skin, the scent of your clothes, and the smell of your home all become part of the emotional foundation your baby builds in the first few months.
