I'm Jack. I've always been Jack, ever since I can remember at least, though I suppose I must have been called 'Baby' for a bit before Serena came. But she's only a year and a half younger than me, and Maud's only a year and a quarter behind her, so I can scarcely remember even Serena being 'Baby'; and Maud's always been so very grown up for her age that you couldn't fancy her anything but 'Maud.'
