How Your Child's Brain Grows

Your child's brain grows the fastest in early childhood

A baby is born with roughly 86 billion brain cells

Almost all the brain cells a human brain will ever need

These brain cells, called neurons, are connected by some 50 trillion connections, called synapses

This synaptic network will ultimately determine how a child thinks and behaves

Synapses grow rapidly during the early years

But not all of them will remain as the brain grows

"Use It or Lost It"

Unused connections will eventually be eliminated. This is called synaptic pruning

This is why some skills are best learned during the critical period in brain development
