Why It Matters: Early Childhood
Why learn about development during early childhood?

Children in this stage are changing from intuitive problem solvers into more sophisticated logical problem solvers. Their cognitive skills are increasing at a rapid rate, even though their brain is beginning to lose neurons through the process of synaptic pruning.
Children are also learning to navigate the social world around them. They are learning about themselves and beginning to develop their own self-concept, while at the same time they are becoming aware that other people have feelings, too. The development that happens in these four years impacts the rest of the child's life in many ways for years to come.
