Somehow, my 14-month-old started identifying several of her own physical features (including "neck"!) by close approximations of their names after only 3 or 4 nights of reading this book before bed. Very shortly after, she started pointing out the same features in pictures of animals and people around the house. The illustrations are crystal clear in their intent, with only the last two pages presenting any difficulty (one covers elbow, arm and chin in one breath, and the other is for skin, which I imagine is tough to illustrate). I would recommend this book to anyone teaching the easy body parts to her/his child.
