brain building begins at birth
at birth, a baby's brain is about one-third the size of an adult's brain. in 90 days, it more than doubles its volume, to 55 percent of its final size. learn more fascinating facts and science about how little everyday moments count to help build a baby’s brain.
the science and stats behind building a child’s brain
the building of a brain begins before birth and continues into adulthood. the process sets the foundation for all the health, learning, and behavior that follow. it’s truly amazing and the impact little moments has on a child’s brain is powerful.
our brain’s ability to change is the strongest in the first few years after birth, making it easier to form strong neural connections than later in life.
brain architecture is shaped by experiences and develops in the context of relationships. when parents and caregivers do “serve and return” activities with a child, their brains form strong neural connections.
simple skills like saying a word or recognizing a color support later developing skills like reading and writing. a weak early foundation affects everything that comes after.
80% brain growth by age 3
at birth, the brain already has all of the neurons it will ever have. it doubles in size in the first year, and by age three it has reached 80 percent of its adult volume. neural connections are formed at a faster rate during these years than at any other time.

a million neural connections per second
a child’s brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second.

hearing 2 or more languages helps with focus
babies who are spoken to regularly in two or more languages have better executive function and focus later in life, specifically better attention or focus, which helps with school and work performance.
