Wahey, it’s a pregnant woman! Roll on in, let’s have a look at you. And now, because we’ve been staring so long, we’d better say something constructive, otherwise it’s going to get awkward. So it’s clear, from the shape of your bump, that you’re having a girl. Or a boy. Definitely one of those.
In truth, we’ve never yet heard a dad do the maternal equivalent of reading tea leaves, but if I had a child for every mum who’s taken a bump-shaped punt, I could start an orphanage.
Actually, as if to prove that not everything can be explained with peer-reviewed research, that last study throws up the finding that while the mainstays of prediction are without foundation – the shape the bump, the prevalence of morning sickness, and also comparisons against previous pregnancies – it turns out that better-educated women are more likely to guess correctly. But nobody knows why. Theories on a postcard please.
Verdict: 100% cobblers
