26. He is Learning Things Grades Ahead of His Age
Your three-year-old is learning to read, even though kids usually learn to read in kindergarten. Or, your five-year-old is learning how to add and subtract numbers when his classmates are still learning what numbers are. Your eight-year-old is teaching herself how to code and even build computer games and apps. If your kid is learning things that are years ahead of his age, then he is a genius, especially if he is learning not just one thing but many different things at an accelerated rate.
