Every new mom knows that her baby understands more than he can say. You say to a baby, “milk!” and that baby brightens right up. Long before he can speak, he understands.
That amazing, ahead-of-the-curve process never stops, as long as kids are constantly challenged with new ideas and offered the chance to learn new skills.
I’m not advocating French flash cards for infants or War and Peace for a toddler. But I am saying that your kids can handle more than you think.
