Playwright Richard Tulloch’s adaptations of children’s books are things of beauty, perhaps none more so than his version of Sam McBratney’s enormously popular Guess How Much I Love You books.

There aren’t many parents of children under 5 who don’t know the story of a couple of brown hares, parent and child, whose affectionate banter about just how much it’s possible to love has made the books compulsory bed- time reading for a generation now, and more.

The success of any venture of this kind is to be found in the audience. Tots from just 3 or 4 years of age were along, many in a theatre for the first time, and the noise was deafening. But as the house lights went down, and Isla Shaw’s design was revealed in all its watercolour beauty, and the house fell silent.
