It all started when busy father Greg Pembroke posted a few pictures online of his three-year-old son, mid-tantrum, alongside the reason his son was crying: He had broken his bit of cheese in half. This book collects together photos sent to Greg from parents around the world, documenting the many, completely logical reasons why small children cry. ('I let him play on the grass' . . . 'We told him the pig says "oink"' . . . 'The neighbour's dog isn't outside'). Together, they are both a fond portrait of the universal, baffling logic of toddlers - and a reminder for burned-out parents everywhere that they are not alone.
