Traditional swim lessons teach certain skills that are contradictory to what we teach. For example, they teach children to blow bubbles when we want them to hold their breath. If your child falls into a pool or gets in trouble with water, we want them to hold their breath, not blow out all of their air. Secondly, traditional swim lessons teach children to be vertical in the water.
We want children to be horizontal in the water (meaning laying on their back or front) so they can actually swim and float. Lastly, traditional swim lessons do not teach children the basic survival skills, like how to independently flip and float to get air when needed, instead they teach children to reach safety first and foremost, at whatever cost (which can lead to panic, strain and or drowning).
We teach children the basics, for water safety and survival, so they can respect the water and when needed know how to safely handle a dangerous situation.
