Book excerpt: 'This isn't just a holiday diary. It's a huge great blockbusting book!' I'm Sadie and I'm nearly nine. Mum's a childminder, but she doesn't have to mind me. I can mind myself, easy-peasy! Lucky for Mum, because now she's got the flu, so I've got to mind her - and help with all the babies! A hilarious, entertaining and lively account, of one chaotic week in the life of a young girl whose mother is a childminder, with a special introduction by bestselling author Jacqueline Wilson.
