Pediatricians often tell new parents that their child's brain is like a sponge from the minute they are born. They soak up everything that's going on around them. Neuroscience research has shown the early years are especially crucial for brain development &kids focus. This period lays the foundation for who that child will become.

From birth to age 5, a child's brain is growing at warp speed. Neurological and brain development in early childhood is shaped by every interaction children have. Even experiences that may seem insignificant to an adult, like meeting a new person, teach a child how to interact with the world around them. That’s because the brain’s size and shape are constantly changing in response to encounters during this period.

During the prenatal period, emphasis is put on genetics (nature). There’s no doubt genes are important. Genes are the blueprint of life. However, environmental stimuli (nurture) are just as important.

In fact, even when the blueprint isn’t great, if a child grows up in a nurturing environment it’ll have a positive impact on brain development. Attentive parenting and proper kids brain nutrition are fundamental factors for brain development & focus.

Early Childhood Brain Development Facts

Did you know a baby is born with billions of neurons? Even more incredible are the trillions of neural connections that link those neurons! Those connections, called synapses, are the foundation on which the rest of the brain will develop. They are formed every time a child experiences something.

Babies are so small and fragile when they enter the world, yet miraculous things are taking place right below the surface of their soft, little heads.

A baby’s brain contains 100 billion neurons when they are born. No wonder moms are tired during pregnancy, their bodies are making all those! While some areas of the brain, like the cerebellum and the prefrontal cortex continue making neurons after birth, what really matters are the connections that carry the information children have gathered up to the nerve cells in the different areas of the brain. For example, when a parent picks up their baby a connection is formed.

When a baby enters the world, they have 50 trillion neural connections, also known as synapses. By the time they reach adulthood they’ll have around 500 trillion.

As a child grows, their brains are rapidly developing new neural connections. We're not talking about 100 new synapses a day, either.

“A toddler’s brain is forming more than 1 million connections every second.”


Research shows that they’ll have roughly 15,000 neural connections per neuron by the time they are age two or three. They started out with approximately 2,500 per neuron. In total, a toddler’s busy brain has about 1,000 trillion synapses.

About those synapses - the neural connections are like interstates carrying the knowledge to and from different areas of the brain. Over time, the brain sheds the neural connections that it isn’t using.

Neuroscientists call that synaptic pruning.

Depending on their experience, the connections formed and kept will determine if they're going to be intelligent, loving, kind, and empathetic, as opposed to ignorant, mean, and selfish. That is why parenting is so critical for kids' brain development & focus.

The relationships kids have and their experiences during the first 3 years of life will have a profound impact on the rest. Even if a child doesn’t specifically remember this part of their life, their brain’s connections do. All this neuron generation, synapse pruning and removal requires energy and nutrients. That is where optimal nutrition comes in. Helping kids get the proper nutrition can be difficult when they are picky eaters and so modern food companies have made herculean efforts to make food entertaining and sweet, which is not always ideal for youngsters.

The Standard American Diet has been shown to fall short when it comes to providing kids with the proper brain nutrition leading many parents to look to supplements to bridge the gap.

Parent/Child Relationship Impact on Brain Development

Imagine a person planted an acorn and grew an oak sapling. The young tree is growing just fine but then the person starts neglecting it. Over the next few years, the tree is given minimal attention and care. When it grows into a young tree, it’s not very attractive. Its leaves are thin and its trunk is scrawny.

Next door to that person’s house, a neighbor also planted an acorn. They watered it every day, fed it plant food, and nurtured it with love and attention. Now it’s a beautiful tree with vibrant, full leaves. The trunk is sturdy and it’s providing plenty of shade for its caregiver.

Now, imagine those trees are humans.

A child who is well-loved, cared for, and fed a rich, balanced diet, has a far better chance of growing into a well-adjusted, successful adult, compared to one who is not

As mentioned, a child’s neural connections are rapidly developing. If a parent is kind and happy for the most part, their toddler is growing "kind-and-happy" connections. As the child ages, those synapses get stronger and healthier. Those connections will follow them to adulthood and they'll know how to build strong, healthy relationships.

The flip side can create children who will have a much harder time fostering healthy relationships in adulthood, or maintaining focus. They could also be less likely to be successful if their parents failed to create a healthy learning environment.

Child Brain Development Timeline

Neurological and brain development in the early years of a child's life occurs very quickly. The brain is creating and pruning connections rapidly. It’s not all happening simultaneously though. Brain development stages differ depending on the age of a child. For example, a 3-month-old baby isn’t going to form the connections that allow them to comprehend abstract thinking. They’re still working on basic motor skills. The abstract thinking comes after their new neurons are built!

There are four important children brain development stages according to French psychologist Jean Piaget:

Kids Brain Development & Focus (2)Sensorimotor Stage (birth to 2 years)

During the sensorimotor stage, children learn about the world using their senses. They touch, smell, lick, bite, and see their way around their world. That's why babies are constantly putting items in their mouths.

When a child is born, their brain is about 25% of the size of an adult brain. It will double in size during the first year of life. By the second stage of development, the brain is roughly 80% of the size of an adult's. Synaptic density reduces to half by age two.

That's why it's critical that parents, caregivers, and others treat toddlers kindly and show them love. There is no “do-over” for this crucial stage of brain development.

Kids Brain Development & Focus (3)Preoperational Stage (Ages 2 to 7)

Cognitive growth is still happening very fast during this stage. By the age of 5, a child's brain will be 90% of the size of an adult's.

Children will usually learn how to communicate in whatever language they will primarily speak during this critical developmental phase. It's the best time to teach them multiple languages because it's easier for a child to learn.

A child will also learn how to think symbolically during the preoperational stage. The ability to focus, short-term memory, long-term memory, logic, and reasoning are all developing during these years.

Kids Brain Development & Focus (4)Concrete Operational Stage (Ages 7 to 11)

Children are more aware of other people's feelings during this stage. They learn to apply logical thought to objects. The neural connections for abstract thinking are not developed during this stage. That's why kids have a hard time understanding the long-term repercussions of their actions.

Kids Brain Development & Focus (5)Formal Operational Stage (Ages 11 to adulthood)

The brain isn't fully developed until it is about 25 years old. Thinking becomes much more sophisticated after age 11 as the experiences a child has strengthen the synapses developed early on.

During this stage, a child learns how to think abstractly. They hone their problem-solving skills and the type of person they're going to become is made clear.

(Brain) Food Matters

Nutrition and healthy brain development go hand-in-hand during the early years of a child's life. If the right brain nutrition for kids is missing, a child's brain will not grow properly. That's why you'll notice many baby formula and food are enriched with nutrients like iron.

Researchers at the University of Minnesota School of Medicina have found that various nutrients support specific brain functions and development. Vitamin deficiency could have a profound and lasting negative impact on a brain.

Kids Brain Development & Focus (6)

According to Harvard Health, the first 1,000 days of a child's life are particularly important. The brain is busy creating its neural connections between the billions of neurons floating around in there.

If a child is fed unhealthy food devoid of balanced nutrients, their brain will not be able to function properly or achieve its true potential. The child’s ability to focus will decrease and the important neural paths the brain is creating will slow. A deficiency can also affect the size and complexity of cells.

Bridging the Nutritional Gap for the Brain With Rich Supplements

In order to support kids' brain development & focus, some parents may turn to nutritional supplements formulated for kids' brains. Ideally, getting everything a kid needs from whole foods would be great, but the amount of nutrients that the brain needs are hard to obtain from the standard American diet consistently. If mom and dad have a picky eater on their hands, feeding the brain properly without supplementation is near impossible.

Kids Brain Development & Focus (7)

Supplements, like our Kids Brain Boost smoothie, allows parents to sneak brain foods for kids into their diets without the squabbling. Busy parents can give their toddler one nutrient-packed snack that will promote healthy brain growth. If they have an older child, supplementing their diet with healthy snacks that allow them to sneak their vitamins in will help their child focus and get better grades.

What should they be eating?

Well, there are specific ingredients proven to promote healthy brain growth in children.

Omega 3s

Omega 3s are thought to be the building blocks of neurological development. Kids who get the proper amount of omega 3s are at a decreased risk of developmental delay. They often have better communication skills and fewer behavioral problems.

Researchers have also found kids who eat foods rich in omega 3s have improved cognitive function and development.


This nutrient makes sure that the blood vessels in a child's body are flexible and strong. By helping the blood move through the child's body safely, the brain is able to build the connections it needs for the future.


Iron is extremely important brain food for kids. The body uses iron to develop the central nervous system and help a brain function. Neurodevelopmental studies found the nutrient helps develop neurotransmitter systems, as well. If a child does not get the proper amount of iron, it can lead to lifelong neurological delays.


This is another essential nutrient for brain development in the early years. Uridine helps with membrane synthesis in the brain. Combined with choline and the omega 3 fatty acid DHA, uridine helps determine how many synapses will grow in the brain.

Vitamin C

This antioxidant helps with many bodily functions including cognitive function and the growth of connective tissues and blood vessels.


Brains need protein to produce neurotransmitters that will carry messages to the different parts of the brain using the connections developed in a child's early life.


Curcumin boosts the growth hormone responsible for memory and learning. The nutrient also supports a healthy response to inflammation, including inflammation in the brain.


If a child is not getting enough choline, brain development will be impacted. It is an essential vitamin for human beings. Research from Oregon State shows that this neurotransmitter is involved in memory and muscle movement. Choline deficiency could also lead to cognitive deficits.

Start Making a Difference Now!

First and foremost, the most important thing parents, caretakers, and other attentive family members can do to help children's brain development is to show them love. Hug kids and spend time with them. Encourage kids while they are trying and learning, especially in their early years.

Kids Brain Development & Focus (8) Nourish Your Kid with Rich Brain Food

We are what we eat. Provide your child with a balanced diet and supplement the key brain nutrients that are hard to obtain at ideal amounts from regular foods. You’ll supply the building blocks for a brain that will help behavior, focus, and grades.

Kids Brain Development & Focus (9) Be Understanding

Understand that children who are 2 years old have no self-control and it's not on purpose. Their brains haven't developed those connections yet. Patience will go a long way and all of the affection adults show children while they are young pays off long-term.

Kids Brain Development & Focus (10) Read, Read, Read

Adults should read to children every day. Studies have found that children whose parents read to them regularly as babies have better vocabularies and higher language skills than kids who were not read to. If a parent reads five books a day to their child, a study found their kids will have heard 1.4 million more words than a child who wasn't read to.

Kids Brain Development & Focus (11) Play Games

Parents should play games with their children in the early years to teach them critical thinking skills. Researchers suggest reading to kids and then connecting the book to an experience the child has had to help them draw parallels. Mom and dad can then play a game with them and have the child name some differences between their experience and the book's story.

Kids Brain Development & Focus (12) Get Down on the Floor

Adults need to get down and play with their children. Even if it's just to help them build blocks or fit shapes in the holes in a bucket. Activities like these are great for cognitive function. They also give parents an opportunity to connect with their children on a very basic level.

The child will see that mom and dad are interested in their life and it'll help them form healthy neural connections.

Kids Brain Development & Focus (13) Introduce Babies to New Things

Taking a baby out of the house and letting them use their senses to explore the world around them will optimize brain development. They should play in the grass and grab it with both of their hands.

Parents should bring their little ones to nature and let them pick up acorns or crunch leaves with their feet. Take their toddler to the beach and let them run through the sand and feel it between their toes.

All of these experiences will help their brains develop.

Kids Brain Development & Focus (14) Respond to Your Baby Kindly

Every parent gets frustrated occasionally, but how a parent responds to their child's stress will stick with them forever. Babies cry because it is the only way they can communicate. Go ahead and pick them up when they're upset. When a parent comforts their child, healthy brain connections are formed.

Kids Brain Development & Focus (15)Speak to Them Often

Parents should speak to their babies all the time, even when the child can't talk back. When they are giving their child a bath they should tell the baby what they are doing. If they take their toddler for a walk, mom and dad should point to trees, leaves, grass, people, benches, etc.

If the baby lives in a multilingual household, parents should speak to their toddlers in all of the languages they speak. That helps the child form the connections in the language center of the brain.

Kids Brain Development & Focus (16) Neglecting a Child Is Mentally Devastating

Prolonged neglect leads to problems with language skills, poor grades, an inability to focus and poor relationships with peers. A child whose parents don’t spend time with them, or sit down to eat together, doesn’t grow the important “love-and-nurture” connections in their brain. Busy and neglectful parents are literally causing insufficient neurological development in their child. That trauma will stick with a child for the rest of their life.

Kids Brain Development & Focus (17) Discipline Is Important

Parents should be authoritative and set expectations for children, but not be overly harsh. Understanding healthy boundaries helps the kids develop connections in their brains. Failing to build a child’s discipline is just as damaging as being unkind, but it impacts different synaptic connections.

Help Build Those Synaptic Connections

Every second of a child's life is impacting their brain development. Each experience is as important as the last and all of the moments are creating vital neural connections in their brain. One million connections every single second are formed.

Parenting is critical from the first moment of a child's life. Equally as crucial is the food the parent gives their little one. Brain nutrition for kids will impact brain development in a profound way. If a child is not eating the right nutrients, or not eating them amounts, their brains will not get close to their true potential. Those critical synaptic connections will not form and the rest of the child's life will suffer the effects.

These early years are the most influential on kids' brain development & focus. Think of a child's brain like it's a house. If the foundation is laid properly, the rest of the construction is easier to complete and more resilient.

Early Childhood Brain Development Facts

During the early years of a child's life, their brain undergoes rapid development. The brain's growth and neural connections are shaped by every interaction and experience a child has [[1]]. For example, meeting new people or engaging in various activities helps children learn how to interact with the world around them. The brain's size and shape constantly change in response to these encounters.

Babies are born with 100 billion neurons connected by 50 trillion synapses [[1]]. Neurons are the building blocks of the brain, and synapses are the connections between neurons. At birth, a neuron has an average of 2,500 synaptic connections. However, by the time a child reaches adulthood, they will have around 500 trillion synapses [[1]].

Neuroscientists refer to the process of shedding unused neural connections as "synaptic pruning" [[1]]. The connections that are formed and kept in the brain depend on a child's experiences and environment. Attentive parenting and proper nutrition are fundamental factors for brain development and focus [[1]].

Parent/Child Relationship Impact on Brain Development

The relationship between parents and children has a profound impact on brain development. Research suggests that children who receive love, care, and a balanced diet have a better chance of growing into well-adjusted and successful adults [[1]]. Positive experiences and nurturing environments help children develop healthy neural connections, which are crucial for their future relationships and overall well-being [[1]].

Conversely, neglect and lack of parental involvement can have detrimental effects on a child's brain development. Prolonged neglect can lead to problems with language skills, poor grades, difficulty focusing, and poor relationships with peers [[1]].

Child Brain Development Timeline

Brain development in children occurs in different stages, each with its own characteristics and milestones. According to French psychologist Jean Piaget, there are four important stages of cognitive development:

  1. Sensorimotor Stage (birth to 2 years): During this stage, children learn about the world through their senses. They explore their environment and develop basic motor skills. The brain grows rapidly, reaching about 80% of adult size by the end of this stage [[1]].

  2. Preoperational Stage (ages 2 to 7): Cognitive growth continues, and children learn to think symbolically. They develop language skills and logical thinking. By the age of 5, a child's brain is about 90% of the size of an adult's brain [[1]].

  3. Concrete Operational Stage (ages 7 to 11): Children become more aware of other people's feelings and learn to apply logical thought to objects. Abstract thinking is not fully developed during this stage [[1]].

  4. Formal Operational Stage (ages 11 to adulthood): This stage is characterized by more sophisticated thinking and problem-solving skills. Abstract thinking and deductive reasoning develop further. The brain continues to mature until early adulthood [[1]].

(Brain) Food Matters

Nutrition plays a crucial role in brain development, especially during the early years of a child's life. The brain requires specific nutrients to function properly and achieve its full potential. The first 1,000 days of a child's life, starting from conception, are particularly important for brain development [[1]].

Various nutrients support specific brain functions and development. For example:

  • Omega-3 fatty acids: Omega-3s are considered the building blocks of neurological development. They are important for communication skills, cognitive function, and overall brain development [[1]].
  • Iron: Iron is essential for the development of the central nervous system and brain function. A deficiency in iron can lead to neurological delays [[1]].
  • Vitamin C: This antioxidant supports cognitive function and the growth of connective tissues and blood vessels [[1]].
  • Protein: Protein is necessary for the production of neurotransmitters, which carry messages in the brain [[1]].
  • Other nutrients like transresveratrol, uridine, curcumin, and choline also play important roles in brain development [[1]].

Bridging the Nutritional Gap for the Brain With Rich Supplements

While obtaining nutrients from whole foods is ideal, it can be challenging to provide children with all the necessary brain nutrition through regular foods, especially if they are picky eaters. In such cases, nutritional supplements formulated for kids' brains can help bridge the nutritional gap [[1]].

Supplements like the Kids Brain Boost smoothie can provide children with essential brain nutrients in a convenient and enjoyable way. These supplements often contain ingredients such as omega-3s, iron, uridine, vitamin C, protein, curcumin, and choline, which support brain development and focus [[1]].

Help Build Those Synaptic Connections

Parents and caregivers play a crucial role in helping children build healthy neural connections. Here are some ways to support brain development:

  • Show love and spend time with children. Encourage and support them during their early years [[1]].
  • Provide a balanced diet and consider supplementing with brain-boosting nutrients [[1]].
  • Be understanding and patient, especially with young children who are still developing self-control [[1]].
  • Read to children every day to enhance vocabulary and language skills [[1]].
  • Engage in play and games that promote critical thinking and problem-solving skills [[1]].
  • Get down on the floor and play with children, fostering cognitive function and forming healthy neural connections [[1]].
  • Introduce babies to new experiences and environments to optimize brain development [[1]].
  • Respond to a baby's needs kindly and comfort them when they are upset, as this helps form healthy brain connections [[1]].
  • Speak to babies and toddlers often, even if they can't respond. This helps develop language skills and connections in the brain [[1]].
  • Set healthy boundaries and provide discipline, as it helps children develop important neural connections [[1]].

Remember, every second of a child's life is impacting their brain development, and positive experiences and nurturing environments are crucial for building vital neural connections [[1]].
