Aroma Sensitivity: Babies' Superpower In The Womb

A baby's sense of smell is one of the first senses to develop, with their olfactory receptors forming as early as 8 weeks into pregnancy. By the time they are born, babies can smell about as well as adults. They are able to recognize their mothers by scent alone, and this is crucial for bonding. In addition, a baby's sense of smell helps shape their food preferences later in life.

Babies' sense of smell develops in the womb

Babies are born with a complete sensory system, including the sense of smell. This sense starts developing in the first trimester of pregnancy, with two tiny nostrils appearing just a few weeks after conception. By 10 weeks, the olfactory receptors that the baby will use to detect smells have already formed.

Babies start using their sense of smell while still in the womb, breathing and swallowing amniotic fluid, and becoming familiar with its scent. This is useful because the smell is similar to that of their mother's breast milk, which they'll need soon after birth.

The amniotic fluid also carries the scent and flavours of the food the mother eats, so the unborn baby will be familiar with these aromas, too. Research has shown that babies exposed to certain foods in the womb, such as carrot or garlic, will later show a preference for them.

By the time they are born, babies can smell about as well as adults. They will easily recognise their mother by the scents they detected inside the womb, and this is why they will be drawn to her.

The sense of smell is processed by a part of the brain that also controls memory. It creates strong associations between particular scents and experiences. As a result, years later, a scent may trigger a memory for the baby and remind them of a time or feeling from the past.

Taste and smell are intertwined

Taste and smell are two distinct senses, but they are closely intertwined. Our sense of taste is actually 90% smell. When we eat, molecules in our food make their way back retronasally to our nasal epithelium, meaning that all of what we consider flavour is actually smell. When we eat, our olfactory receptors in the back of the nose bind with the molecules in our food, and this information is sent to our brain via the olfactory nerve.

Our sense of smell is responsible for about 80% of what we taste. Without our sense of smell, our sense of taste is limited to only five distinct sensations: sweet, salty, sour, bitter and umami. All other flavours we experience come from smell. This is why most foods seem bland or tasteless when we have a blocked nose from a cold.

Taste buds start developing around 8 weeks into a pregnancy, but the baby won't utilise this sense until around 15 weeks. At this point, they will be swallowing amniotic fluid, which contains molecules from their mother's meals. They will be able to "taste" some stronger flavours, such as spices and garlic.

Babies start using their sense of smell while still in the womb. As they breathe and swallow amniotic fluid, they become familiar with its scent and that of their mother. This is useful because the smell of amniotic fluid is similar to that of their mother's breast milk, which they'll need soon after birth.

Babies are born with a highly developed sense of smell, and it influences what they do and don't like to eat. Familiar smells, including their mother's scent and the aroma of their favourite places, are comforting to babies and play a role in bonding.

Babies can recognise their mothers by scent

A baby's sense of smell is one of the first senses to develop, with their olfactory receptors forming as early as 8 weeks into pregnancy. By the time they are born, babies can smell almost as well as adults.

Babies start using their sense of smell while still in the womb. As they breathe and swallow amniotic fluid, they become familiar with its scent, which is similar to the smell of their mother's breast milk. The amniotic fluid also carries the scent and flavours of the food the mother eats, so the baby will be familiar with these aromas before birth.

Newborns have a highly developed sense of smell. Although they can't recognise their mother by sight, they will know her by her natural scent, and this is what they will most want to smell. They will also be drawn to the scent of their mother's breast milk. These smells are connected to their basic needs for comfort and food.

The sense of smell is processed by a part of the brain that also controls memory. It creates strong associations between particular scents and experiences. This means that, years later, a scent may trigger a memory for the baby and remind them of a time or feeling from the past.

Babies whose mothers ate a lot of star anise during pregnancy enjoyed the smell once they were born, while those whose mothers had not eaten star anise did not. This suggests that a mother can influence her baby's likes and dislikes through her dietary choices.

When a baby is born, they will be able to recognise their mother simply by her smell, due to the fine-tuning of their nose in utero.

Babies can smell food in the womb

Babies' sense of smell is one of the first senses to develop, with their olfactory receptors forming as early as 8 weeks into pregnancy. By the time they are born, babies can smell about as well as adults.

Babies start using their sense of smell while still in the womb, breathing and swallowing amniotic fluid and becoming familiar with its scent. This is useful because the smell is similar to that of their mother's breast milk, which they will need soon after birth.

Babies' sense of smell starts developing early on in pregnancy. Around weeks 6 and 7, olfactory receptor neurons that help the baby's brain process odours develop. Two symmetrical nasal cavities that form the foundation of the baby's nose also form in the first trimester. These nasal passages will then open and connect the baby's mouth to its nostrils.

Since what a pregnant woman eats gets passed on to her amniotic fluid, her baby not only tastes but also smells some of the foods she swallows during late pregnancy. When pregnant women eat certain strong-flavoured foods during the last months of pregnancy, newborn babies recognise the odours immediately after birth, indicating that the baby detects and remembers these scents in the womb.

Babies generally prefer sweet flavours, which makes breast milk more appealing to them. However, amniotic fluid isn't just sweet. Research has shown that strong flavours from the foods eaten by the mother are also present. Repeated exposure to these flavours can influence a baby's enjoyment of them once they start weaning.

In one study, mothers-to-be were asked to drink a lot of carrot juice in their third trimester. When their babies began weaning months later, they enjoyed carrot-flavoured cereal more than the control group whose mothers hadn't had the juice.

The sense of smell is processed by a part of the baby's brain that also controls memory. It creates strong associations between particular scents and experiences. As a result, years later, a scent may trigger a memory for the baby and remind them of a time or feeling from the past.

Babies can also recognise their mother simply by her smell. This is because some of the same chemicals, including a few coming from the foods the mother eats, are found in her amniotic fluid, skin, and breast milk.

Babies can smell breast milk

Babies have a strong sense of smell, which they develop in the womb. This sense of smell is one of the first senses to form, with development starting as early as six to eight weeks into pregnancy. By the time they are born, babies can smell about as well as adults.

Babies start using their sense of smell while still in the womb, breathing and swallowing amniotic fluid, and becoming familiar with its scent. This is useful because the smell is similar to that of their mother's breast milk, which they will need soon after birth.

The tiniest newborn babies can sniff out breast milk and even lactating women because breast milk has very specific fragrances that are extremely attractive to babies. Infants can also recognize their own mothers simply by smell.

This is possible because some of the same chemicals, including a few coming from the foods the mother eats, are found in the amniotic fluid as well as the mother's skin and breast milk. It is important for the baby to be able to recognize and rely on the mother for meals, comfort, and love from day one.

Babies are born with an instinct to suck and root for food, but a newborn's sense of smell is a strong sense that helps a baby bond with its parents. While the baby can smell both parents, it can also detect the distinct smell of its mother's milk. By simply holding your baby near your chest, she'll turn her head and root for your breast if she's hungry. This is nature's design for a strong nursing relationship.

Babies can smell their mothers from up to two feet away. In the first few days after birth, the mother's body produces a sweat similar in scent to amniotic fluid. Considering that the baby has been able to suck and swallow since around five months, it makes sense that when you put the baby on the mother's chest after birth, the baby will find its way to its next site of nutrition: the mother's breast.
