while watching this i was wondering about this "babies born tail first so they can breath" thing....
my thoughts are as follows :
dolphin skeletons and spines favour the forward movement ...
so a baby skull would be inconvenient if placed in such a place that it interfered with the mothers movement while bringing that baby to life... in the womb etcetera.
so the best answer should be that the baby is best advantaged while copying sympathetically the movements of mother as she swims , during pregnancy and during birth..
since because of the shape of the tail it might make it harder to birth tail first ... but then pushing on the head while the baby is inside to push it out would probably make more sense from a physics opinion.
