This causes the visible “seesaw” breathing pattern in which the chest and abdomen alternate movement. B) INCORRECT. Although a child’s cricoid cartilage and trachea are softer and more flexible than those of an adult, they generally will not cause a “seesaw” breathing pattern. C) INCORRECT. The proportionally larger tongues of children do not contribute to the “seesaw” breathing pattern. D) INCORRECT.
