Ball hit by Mickey Mantle on April 17, 1953 at Griffith Stadium to set a new distance record for home runs. (Courtesy the National Baseball Hall of Fame) The longest home run ever hit did not go 565 feet. Not even close. Actually, the longest home run ever hit isn't even the longest home run ever hit.
At the minimum, a baby must be able to hold his head up steadily and have his feet touch the floor to use a walker. Walkers are designed for use by infants between the ages of 4 and 16 months, according to Consumer Reports, and children who can already walk should not use them.
Lots of factors affect the timing of first steps, from heredity to body size. And though half of all kids are toddling by their first birthday, most pediatricians don't consider a child to be a late walker until he's 15 months old. Even then, one in ten children takes his first steps between 15 and 18 months.
