Most scientists and child development experts agree that 90% of your child’s brain capacity develops before he or she reaches age 5! 

By age three, a child’s brain has formed 3 quadrillion connections. Wowza!

An average 3-year old has a vocabulary of 900 words which amounts to a three time increase from when he was 2. Imagine that a 4-year old’s brain is twice as active as an adult’s.

This means you new parents have to not rest on your laurels and do your part to not waste all that good active brain capacity.

Here is an infographic that breaks down your little rocket scientist’ noggin some more so you can determine if he’s on target with his age, although all children develop at varying pace and levels.
