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.
Retailers must give you clear safety guidelines when selling a baby walker. Baby walkers must comply with the standard BSEN 1273:2005. If someone suggests a walker for your baby, look at other toys suitable for your baby's age first. Good alternatives for active and curious babies are baby play stations or static exercisers. Or, you could just let your baby exercise on the floor.
