Children’s brains develop in spurts called critical periods. The first occurs around age 2, with a second one occurring during adolescence. At the start of these periods, the number of connections (synapses) between brain cells (neurons) doubles. Two-year-olds have twice as many synapses as adults. Because these connections between brain cells are where learning occurs, twice as many synapses enable the brain to learn faster than at any other time of life. Therefore, children’s experiences in this phase have lasting effects on their development.

This first critical period of brain development begins around age 2 and concludes around age 7. It provides a prime opportunity to lay the foundation for a holistic education for children. Four ways to maximize this critical period include encouraging a love of learning, focusing on breadth instead of depth, paying attention to emotional intelligence, and not treating young children’s education as merely a precursor to “real” learning. 

Young children need to enjoy the process of learning instead of focusing on performance. Educators and parents can emphasize the joys of trying new activities and learning something novel. We need to help children understand that mistakes are a welcome, normal part of learning.
