It was just a sort of twisted logic. We don't have e space or money for the twins, so why not go ahead and have another. Sort of on the basis that the only reason NOT to want lots of gorgeous cuddly kids was the practical, sensible stuff like affordability. And also our standards have long since dropped sufficiently that wrangling 3 under 3 was just about manageable. That's why, for instance, I was always the mother doing e school drop in at least one child in pyjamas. And even worse, on occasion, the pick up too!
