The best place to start learning to swim is usually considered the bath, then the swimming pool, however, with 30 years of exploring, talking, watching and observing its clear the best place to start is the shower!! Every time you have a shower allow the water to drip into your mouth and then dribble it out as much as possible with soft lips, cheeks and surrounding face and neck muscles. This is often helped by doing your teeth in the shower. Every time you have a shower take time to feel the sensation of the water dripping/running/flowing down into your mouth or anywhere on your body (skin). This will allow you to start accepting the water and not fight it. Fighting does not allow you to breath easily. Fighting blocks your airways and accepting provides for open airways. A natural flow like land breathing!
