Of course, babies don't plan these things, they just get on with it. But somehow it always seems to happen at the worst possible moment. Brand new coat, favourite skirt, freshly dry-cleaned suit. And, usually, out and about so you're left fumbling for the wet wipes and hoping no one noticed.
But as the mother of a baby who liked to do 'a little sickie' as it's known in our house, I learned damage limitation is possible. Victoria broke fashion's number one rule: never wear black.

I hadn't even walked to the end of our street when, whoosh, our baby was spectacularly sick, throwing up right out of the pram, across the cover and almost onto my feet.
