Perfect for fans of Mary Poppins and Nanny McPhee, this classic series is all about learning and problem-solving. Young readers will love this book.

Meet Mrs. Piggle-Wiggle! She lives in an upside-down house with a kitchen that is always full of freshly baked cookies. She was even married to a pirate once! Best of all, she knows everything there is to know about children.

When Mary turns into an Answer-Backer or Dick becomes Selfish or Allen decides to be a Slow-Eater-Tiny-Bite-Taker, Mrs. Piggle-Wiggle has the perfect cure. And her solutions always work, with plenty of laughs along the way. This is the book that started it all!
