Flotation devices give children a false sense of security and hold them in postures that are not compatible with swimming skills. If a child learns that he can jump in the water and go into a vertical posture and he will be able to breathe, he is getting the wrong idea about that environment. Flotation devices are for children who cannot swim. Children, who cannot swim, should not be allowed to learn that it is safe to play in the water while relying on a crutch. Life jackets must be worn in a boat or around the water when there is the potential for a submersion as a result of an accident i.e. a boat collision or capsize; they are not a substitute for the ability to swim or for adult supervision.
