Why the First 5 Years Are Important for Child Brain Development

As many parents are aware to some degree, the early years of a child's life are vital for brain development. What are some of the reasons that the first five or so years of a child's life are especially important for brain and cognitive development?

At Devlin's Child Development Center, we're proud to offer the best preschool, after-school care, and various other child care programs for families around Sandy, with staff who are committed to your child's safe, effective development. Here are some of the neuroscientific basics on why the first five or so years of a child's life are so vital for brain development, plus some ways that both parents and child care centers alike can promote these themes and encourage quality development.

90% of Brain Development Happens By Age 5

Did you realize that, per several major research studies, around 90% of brain development occurs within the first five years of a child's life? It's true! This means that these early years are crucial for laying down the foundation for all future cognitive, physical, and emotional growth. A child's experiences during this time period shape their overall brain structure and functioning, impacting everything from language acquisition to problem-solving abilities.

For most children, the rate of brain growth in these years is remarkable. The brain doubles in size in the first year of a child's life, then reaches nearly 80% of adult size by age 3, and as we noted, 90% of that size by age 5.

Now, different parts of the brain develop at varying speeds, and not all functions emerge at the same time. For instance, the frontal lobe - responsible for decision-making, problem-solving, and impulse control - doesn't fully develop until young adulthood.

But many crucial capabilities are already formed in early childhood. The auditory cortex (which helps with hearing), visual cortex (vision), and sensory cortex (touch) grow rapidly starting during these years to support developing language skills.

How Brain Development Impacts Every Other Form of Development

It's important not to think of child brain development as an independent factor, separate from other areas of growth. All aspects of development are interconnected and influenced by the developing brain.

Here are just a few examples:

• Emotional Development: The emotional regulation center of the brain (amygdala) develops during early childhood and is responsible for managing emotions such as fear, anger, and pleasure. As this area grows and matures, children become better at controlling their emotions and responding appropriately to situations.
• Physical Development: The motor cortex in the brain controls movement and coordination. As it develops during early childhood, children gain more control over their bodies and are able to engage in physical activities with greater skill.
• Social Development: The prefrontal cortex, which is involved in decision-making and social behavior, also continues to develop during early childhood. Children begin to understand and navigate social interactions more effectively, such as sharing, taking turns, and empathizing with others.
• Communication Skills: Language skills also continue to develop during this stage. Children learn new words and improve their ability to use language to communicate their thoughts and feelings.
• Cognitive Development: The brain's prefrontal cortex plays a crucial role in cognitive development during early childhood. This area is responsible for executive functions such as problem-solving, planning, and decision-making. As it develops, children become better at understanding cause-and-effect relationships and using logic in their thinking.

Importance of Caring, Responsive Relationships

For all children in these vital ages where brain development is at its highest, the presence of a caring and responsive adult is crucial. This type of relationship establishes a strong foundation for healthy social-emotional development, leading to positive outcomes in other areas such as academic achievement and overall well-being.

Caring, responsive relationships help children develop secure attachments, which are essential for their emotional and psychological well-being. These relationships provide children with a sense of safety and security, allowing them to explore their surroundings confidently. As they engage in play and interact with others, children learn about emotions, empathy, and social skills from these experiences.

Whether we're talking about parents, other family caregivers, child care professionals, or any other adult, responsive relationships are crucial for a child's healthy development.

And at Devlin's Child Development Center, our team of child care experts recognizes this. We strive to foster positive, nurturing relationships with every child in our care. Our teachers and caregivers are trained to respond appropriately and sensitively to each child's individual needs, ensuring they feel safe, seen, and understood.
