Pirates Don't Change Diapers

More about the book

When the pirate crew turns up at Jeremy Jacob's house and accidentally wakes his baby sister, that wee scallywag howls louder than a storm on the high seas. Sure, there's buried treasure to be found, but nobody's digging up anything until Bonney Anne quits her caterwauling. So, quickly, Braid Beard and his pirates become babysitters.
