Breaststroke kick with both legs

The child pushes off from the pool wall and swims vertically in the water. They then begin performing a breaststroke-like kick with both legs, which resembles a simplified breaststroke kick where the knees are never fully drawn in. This preparatory exercise introduces a familiar element (the breaststroke kick) in a new form (vertical position). Since the breaststroke kick is the closest to treading water among all previously learned kicks, it is particularly effective for quickly introducing the concept of treading water.
