From the moment you're expecting, your baby’s brain is growing at an incredible pace—over one million new neural connections every second. 90% of brain development happens in the first 5 years of life. That means the time from pregnancy through age five is a once-in-a-lifetime window to support learning, bonding, and healthy development. With simple, loving routines and everyday interactions, you can give your child a strong start that sets them up for lifelong success.
