How fast, can a nine year old be taught to swim? Would the kid learn faster because he is young and has a lot of stamina? Would a kid be a fast swimmer if he learns from this age? There are twins who love the water, they are planning o becoming marine biologists when they grow up. These children are joining swimming classes soon; I also want to know how to teach a child to swim. What are the best ways for the child to know swimming? Is it easy? How much time would it to take to everything about swimming, how much stamina is required?
