Pregnancy is a uniquely intimate relationship between two people. All of us luxuriate in this relationship once, and half of us are lucky enough to be able to do it all over again a second time, from the other side as it were. Never again outside of pregnancy can we be so truly intwined with someone else, no matter how hard we try.
