Just FYI, babies before they are born do not have collapsed lungs. The
lungs have some fluid in them. Hence the risk of having babies gestate
for too long of a time, they may pass their first bowel movement in their
amniotic fluid and subsequently end up with some of it in their lungs,
where it remains at birth and causes serious problems. At birth, air
rushes in as the refill after being squeezed somewhat thru the birth
canal.

Just some info.
