When I knocked a chimney out of my house last year, did I reckon I knew better than my structural engineer? Did I tell him I'd read an article in the Sunday supplements recommending balsa wood instead of steel? I wouldn't be here if I had. So what on earth makes me think I should tell my doctor - who has studied for at least seven years to get where she is - that I know better.
The arrogance is stunning, the stupidity is off the scale. But give the mother of a newborn something to fight against and logic is history.
