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.
Walkers won't help your baby learn to walk. Using one too much may even delay her development slightly. Your baby needs to learn to roll, crawl, sit and to play on the floor, in order to reach her developmental milestones. 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.
