Kerre McIvor: Thank you, Kate, for looking as you should

There's nothing like a good-news story. The safe birth of any much-wanted baby is cause for celebration, so like many others around the world I enjoyed seeing the images of the young Duke and Duchess of Cambridge with their new baby, George.

I especially liked seeing the Duchess' post-baby tummy. In an age where women are booking in caesareans and tummy tucks at the same time; in an age where new mums are exhorted to wear uncomfortable post-pregnancy girdles and corsets (Jessica Alba swears by them, as does Gwyneth Paltrow), it was great to see a woman looking as she should 27 hours after giving birth.

Oh sure, the hair was blow-waved and makeup applied, but that's hardly excessive. I was just so pleased that the Duchess hadn't tried to squeeze herself into a pair of Spanx.

It's infuriated me over the years watching silly celebs shoehorn themselves back into size 6 jeans within weeks of giving birth.

It sends a totally unrealistic message to new mums - and dads.

Within 24 hours of Prince George's birth, OK! magazine had a front cover promising details of the Duchess' weight-loss regime and a headline from her trainer assuring readers that the Duchess's stomach would shrink back into shape.

That has led to a backlash on social media and women are being urged to boycott the magazine.

Having a baby isn't licence to become a sloppy heifer but it is an opportunity to appreciate what your body can do - grow a human, deliver it safely and feed it.

It can go back to being a suitable frame for clothes once the essentials are taken care of.
