Reading this book with my 5 year old daughter, I noticed that the author had encountered the same problems as me and like many parents. For example the fact getting back constantly by our little ones when we tell them "bowl" while it is a "plate" ... this mhorripile but the vocabulary is still the vocabulary. Call objects by name. Throughout the pages, we discover the main rules to follow and they were quickly adopted by my daughter because "MOM you realize it's written on a book so it's true." This book is a good teaching aid. I do not think it was as big and as strong. A nice gift to do.
