What causes the "seesaw" breathing pattern of young children?

A greater reliance than adults on the diaphragm during breathing.

Explanation:

A greater reliance than adults on diaphragm during breathing in young children leads to a characteristic "seesaw" breathing pattern, where the thorax sinks while the abdomen rises and vice-see. This leads to the abstraction of air passage and a hoarse noise when breathing.

This breathing pattern makes breathing inefficient and the patient may need noninvasive and in some cases invasive ventilatory assistance.
