To ensure toddler appeal, Peepo! has repetitive rhymes, holes in the pages, lots of fun stuff to look for, and the most traditional plot of all. We watch a small baby get up, eat his breakfast, go to the park with his sisters & his grandma, have his tea & a bath, and go to bed. So your baby or toddler will find this book familiar and comfortable. Meanwhile, grown-ups and older children will realise that the book is set in the middle of the Second World War. Daddy is in uniform, zeppelins fly overhead, and the paraphernalia of the forties is everywhere. And through all this, the children and adults behave, well, exactly like children and adults do now. The plethora of tiny details keeps grown-ups satisfied for repeated re-readings, and as your child grows more aware of the differences, Peepo! could be a starting point for a discussion of history. Most of the objects in the book are familiar in type but not in style. For example, the bath is tin, and sits in front of the fire, which is full of coal. And there are a few things - like a gas mask - that will be completely unfamiliar to your child. So there is plenty to talk about here. I'd recommend the board book edition - easier for little hands, especially given the holes in the pages.
