Brain Development Text Header

The first three years of life are a period of incredible growth in all areas of a baby's development. A newborn's brain is about 25 percent of its approximate adult weight. But by age 3, it has grown dramatically by producing billions of cells and hundreds of trillions of connections, or synapses, between these cells. While we know that the development of a young child's brain takes years to complete, we also know there are many things parents and caregivers can do to help children get off to a good start and establish healthy patterns for life-long learning.
