Mum and Dad have LOTS of rules. But when we go to Grandma's house, it's a different story … Eating your five a day, tidying up and, of course, going to bed on the dot – it’s only ever the best behaviour with Mum and Dad. And when we go to Grandma’ house it’s just. the. same. Well, sort of. With a twist. Who said anything about drum kits, staying up late and dressing up? This brilliant new picture book story is full of humour, cheeky illustrations and family fun!
