It's Trumpet's birthday, but he is feeling rather out of sorts.... and soon a bit of bickering with his sister Tilly escalates into a giant tantrum! "Calm down, Trumpet!" everyone cautions him, and his mother teaches him to count to ten. Eventually, Trumpet manages to tame his temper. But when his mum loses her own temper, it's Trumpet and his friends who get the last laugh! Another delightful picture book from the dynamic duo who created GILBERT THE GREAT, this funny, charming story is sure to be a winner with toddlers and parents alike.
