If only that were always true. Twin to Twin Transfusion Syndrome and Twin Anamea Polychthaemia Sequence are pretty horrible things that happen not infrequently in monochorionic (identical) twins.

The shared blood bit, yes it can happen. But only in monochorionic (identical) twins, so you don’t get the “wrong” hormonal exchange I suppose.
