This well-worn book has been kicked-around, chewed on and well-loved by my young children since my second oldest received it for Christmas just before the birth of his new baby sister (he was two at the time). The book is a photo-story of the author's daughter as she grows from a new baby to an active toddler. Each two-page shows a number of pictures of the baby doing whatever she does best at that given age. It's a very simple idea, although with my adult fussiness I would only complain that the pages are a bit busy and I sometimes wonder if my very young children understand that all the pictures are of the same baby.
While not a board book, the pages are extra thick and have held up pretty well considering the wear-and-tear in our household. In fact the only major damage so far is that the front and back end-pages have been torn-off (which happily did not damage the actual text of the book). This is really a pre-preschool book (Ages 1 - 4).
