To start swimming, begin by getting comfortable in the water, learn to float, practice kicking, and then progress to stroke techniques. It's often best to take lessons from a qualified instructor.

Teaching a child to swim involves water acclimatization, teaching basic movements like blowing bubbles, floating, basic leg and arm motions, and gradually moving to more complex swimming strokes under supervision.

A beginner should start with water safety basics, get comfortable being in the water, and then gradually learn floating, kicking, and basic strokes. Starting with lessons at a local pool is highly recommended.

Best practices include warming up before swimming, using proper technique, staying hydrated, breathing correctly, and cooling down after your session. Consistent practice and professional coaching can also significantly help.

For basic swimming, you'll need a swimsuit, goggles, and a swim cap. Additional training aids can include kickboards, fins, and pull buoys for more advanced training.
