Meet Jack. Dadness - women have a sixth sense for it. To them, you're like an old bull in a field, watching the world race by. But, lately, as I've looked around, all I've seen is temptation. Meet Amy. Motherhood, I've discovered, is the great leveller. I could be a celebrated fashion designer, but having kids automatically makes me the same as all the other mums up the park. And being 'the same' makes me want to do something terrible rash. Can Jack and Amy resist the seven year itch?
