Wee William is the smallest in his family. Everything about him is small, as his other family members are keen to point out. 'Your tiny ears', says Daddy. 'Your teeny whiskers', says his big sister Martha. 'And your little wriggle', says Mummy. This is something William does when he's out and about, doing all those things that toddlers do-feeding the ducks, swimming lessons, shopping with Mummy. But when Mummy or Daddy see him start to give that tell-tale wriggle, each one of these activities may need to be suddenly cut short in exchange for finding-quickly! - somewhere for him to 'go'. Then one day, when he's out playing with his friends, William has a little accident. After some gentle parental advice, William learns the importance of making sure he goes to the toilet before it becomes a matter of urgency. And the story ends with him enjoying all the thrills of the woodland fair without a single wriggle. There's a lovely moment where the fairground ride makes William cry 'Weeeeeee' for all the right reasons!
