Query: Crazy-making!

This book drives me crazy! The buttons will not stay untangled. No matter how many times I try to untangle them, the minute my son opens this book the ribbons get knotted into an intricate rope of ribbons and buttons! If I do not untagle them, the book is rendered useless. Given hindsight I would not re-purchase this book.
