When Ellie Farmer is working her way up a climbing wall, she sometimes plants her foot or reaches her hand just-so and has to squeal down to her parents, as if to say, "Look! I did it!"

Videos of the rosy-cheeked toddler pulling herself up climbing walls zipped across the Internet this week, drawing millions of views on Facebook in just a few days.
