Learn how the numbers illustrate such concepts as the importance of early childhood to the learning, behavior, and health of later life and why getting things right the first time is easier and more effective than trying to fix them later.

 The early years matter because, in the first few years of life, 700 new neural connections are formed every second. Neural connections are formed through the interaction of genes and a baby’s environment and experiences, especially “serve and return” interaction with adults, or what developmental researchers call contingent reciprocity. These are the connections that build brain architecture – the foundation upon which all later learning, behavior, and health depend.
