Baby bump: a stomach swollen to beyond its usual size due to the presence of a fetus. Precise size of bump will vary, dependent on age of fetus, genetic heritage of stomach owner and sheer bloody randomness. And, um, that’s about it as far as baby bumps are concerned, only that’s not saying much. So here are some further facts I’ve compiled, mainly out of annoyance at all the inexplicable admiration that the Duchess of Cambridge is getting merely for having a small one:

  • If you are famous, it is not possible merely to go out and about while in possession of a bump. You “debut” said bump, then “flaunt” it. To be fair, you might then go on to do a nude magazine cover with arms “tastefully” covering your tits but at this point why not? Might as well be hung for a sheep as a lamb.
  • Small bumps are, generally, good.* For instance, if you’re the Kate Middleton-as-was it’s really classy. Reporters can’t shut up about how petite it is, with the Express claiming that Kate “will be the envy of many pregnant women as she’s still modelling a tiny figure despite being six months gone”. Meanwhile reality TV star Kim Kardashian “blooms”, that is to say she is distastefully large. So too are Jessica Simpson, Lara Stone and “Channing Tatum’s wife Jenna Dewan” – pregnant porkers, one and all. Bet William’s relieved he didn’t pick one of them to produce his heir.
  • It is possible to “dress” a baby bump. For instance, in this picture Kate has dressed her bump in a “gorgeous blue cocktail dress”. Unfortunately she’s ended up having to put the rest of herself in it as well – meaning it doesn’t look any different from just her wearing a dress – but it’s the thought that counts, at least until they develop invasive intra-uterine styling.
  • Alongside housing a fetus, one of the main purposes of a baby bump is for use in advertisements for body lotion and financial services. Or any other advertisement seeking comic effect via the owner of a bump grumpily demanding rubbish food combinations in the early hours of the morning.
  • Once you have a baby bump, you are public property in a way that you weren’t previously. People will smile benevolently, even take the liberty of patting your stomach. It’s annoying, yes, but worth remembering that those who beam at you on the bus one week will be glaring at you the next if you dare to stagger on with a screaming newborn. So you still have to “enjoy” it while you can.
  • Baby bumps can be used for making political statements. You could write “100% pro-choice” on yours. Or “future anarchist leader”. Or you could just put “baby on board”, “under construction” and/or “it started with a kiss”. But know that I will judge you for it.
  • Once a baby is born, a baby bump becomes part of what is known as “baby weight” i.e. that weird, liminal fat that clings to a woman’s post-pregnancy body but isn’t really her. According to Grazia, you can “get rid of your post-baby mum tum with the Gowri Wrap […] an elasticated corset that helps restore your pre-pregnancy stomach” and costs £75. Or you can just not. Personally I’d recommend not.

So those are my baby bump facts. Personally I miss having one but do appreciate the whole “being able to lie on your own stomach” thing. And also the “being able to get drunk” thing. And there’s also the “having the actual children around” thing. So yes. Swings and roundabouts, really.

* Small bumps are sometimes rubbish and a sign that you’re a bad mother who’s not taking care of herself aka her baby (see Kate Moss).
