90% of a child's brain has been developed by 3 years- New research spoken about

I have been proactive in staying informed about the latest research and incorporating that knowledge in childcare. The idea that a significant portion of a child's brain development occurs by the age of 3 is consistent with the concept of critical periods and high plasticity during early childhood.


Early interventions and enriching activities during this crucial period can indeed have a profound impact on a child's cognitive, social, and emotional development. Our focus in our stimulating lifelong learning course for nannies helps them understand and plan.  In addition to being informative with parents aligns  the understanding that a child's environment, interactions, and experiences play a pivotal role in shaping their future capabilities.


The early years are foundational for various aspects of development, including language acquisition, cognitive skills, social-emotional well-being, and even physical development. Providing a stimulating and supportive environment that encourages exploration, creativity, and positive social interactions can contribute significantly to a child's overall development.


Continued research in this field will likely uncover more specific details about the mechanisms underlying early brain development and effective strategies for optimising learning and growth during this critical period.


Early childhood is considered a critical period for brain development, during which the brain exhibits a high degree of plasticity. This means that the brain is highly adaptable and responsive to environmental stimuli during this time.

Synaptic Pruning:

Synaptic pruning is a process that occurs during early brain development where unnecessary neural connections are eliminated, allowing the strengthening of important connections. This process is crucial for refining the brain's circuitry and optimizing functionality.

Early Language Development:

Exposure to language and communication in the early years plays a significant role in the development of language skills. The quality and quantity of language input during this period can impact a child's language proficiency later in life.

Social and Emotional Development:

Early experiences and relationships contribute significantly to the development of social and emotional skills. Positive interactions with caregivers and peers help shape a child's ability to regulate emotions, form attachments, and engage in social relationships.

Impact of Nutrition:

 Adequate nutrition, especially during the prenatal and early postnatal periods, is crucial for optimal brain development. Nutrients like omega-3 fatty acids, iron, and other essential vitamins and minerals support cognitive growth.  Offering a Healthy and varied diet is important to help children in all aspects of they development and well being.

Stress and Adversity:

Early exposure to chronic stress or adverse experiences can negatively impact brain development. Conversely, supportive, and nurturing environments can mitigate the effects of stress and promote healthy cognitive and emotional development.

Neuroscientific Advances:

Advances in neuroimaging techniques, such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), have provided researchers with new insights into the dynamic processes of brain development during early childhood.

Interventions and Early Education:

Research emphasises the importance of early interventions and educational experiences to support optimal cognitive, social, and emotional development. High-quality early childhood education programs can have lasting positive effects.
