This book was actually a major helper in the potty training break through! I'm a nanny, and this helped a great deal when potty training my 2 year old girl. Her mother and I worked hard to stick to the "potty rules" of the book, and within just a short period of time VOILA! a potty training pro she became! I would definitely recommend this book to parents/grandparents, nannies/babysitters, or anyone considering taking the plunge into parenthood. What a terrific resource. So glad we had it!
