Kids these days grow up so fast. When I was 19 months old I was stumbling around, playing ring toss, and smashing trucks together. These days 19 months is just early enough to start doing extreme sports, and the extreme toddler movement already has its leader. Check out the jaw-dropping skill demonstrated by this little tyke as it scales this indoor rock climbing wall. By the time this kid is in 2nd grade, it’ll be free-climbing mountains with the pros. We can only imagine how hard it is to keep this kid in its crib at night.
