January Jones – Betty in Mad Men – turns out to be a bit of a hippy. "With a name like that?" I hear you say, "Who'd have thought it?" She says that women should eat their placenta after childbirth, and insists that doing so helped her to avoid depression and fatigue.

As someone who still remembers the cup and tea and piece of toast I got after having my first baby as the most delicious and wonderful things I have ever tasted, I'm not convinced. Placenta wouldn't have been nearly as nice.

January demurs: it's not, she says, "gross or witchcrafty". Possibly not. The actress had her own placenta dehydrated and made into capsules. Frankly, if you have enough staff available for such obscure tasks to be done on your behalf in the immediate wake of your first child being born, I can only suggest there may be another reason to explain how January managed to avoid those feelings of post-natal fatigue.
