Because such things weren't talked about much when I was young, I was actually middle-aged before I realised that pregnancy was quite a complicated and perilous business.
For a long time I thought it was all very simple - you got pregnant and then nine months later out popped the baby. What was all the fuss about? Why were mothers always congratulated for doing something so routine?
It gradually dawned on me that pregnancy was in fact quite a trial. Every stage can be problematic. You can fail to conceive, fail to remain pregnant, fail to have a healthy diet or a healthy lifestyle. The baby can be premature, or defective, or harmed by medical mistakes, or suffer a cot death.
So if you manage to overcome all those hazards, congratulations are very much in order. Hardly a case of "out pops the baby". More a case of surviving a tough obstacle course against all the odds.
So I welcome the increasing trend to be more candid about pregnancy and all its difficulties. It means I'm much more aware of the ordeal women may be privately going through, however straightforward it may all seem from the outside.
I'm amazed that after all the problems of pregnancy, women don't always say "that was dreadful - never again" but are often willing to go through it several times to satisfy their burning desire for children. I can only admire their unflagging determination.
I'm very glad pregnancy is something that only happens to other people.
