My 2 year old boy is a fan of trains because it has a "privileged" view of the tram. So I was looking for a simple book showing several types of trains. This book is the only one that meets my criteria to his own. The images are beautiful and well done. It is much appreciated even if the pages are fragile for a child his age. For now, I handle it with him but the book is certainly ideal from 3 years.
