During the first 4 to 6 months of life, the infant is an obligate nose breather. In simplistic form, the airway from the nose to the larynx is wide open. It does not take much skill to breathe this way. As the tongue starts falling back into the mouth, and the epiglottis starts to descend, breathing becomes more complex because of the space created between the soft palate and epiglottis.
