In brief: Surfactant
It has more to do with the development of the lungs.
They are not developed enough to stay open and hold air/oxygen well enough. During late pregnancy the baby's body produces what is called surfactant and it helps the lungs expand and stay open with out collapsing so that air/oxygen can go through the lungs.

In brief: Often not developed
It is not size - often the lung tissue itself is not developed.
