The title says it all. National Geographic Little Kids First Big Book of Dinosaurs (National Geographic Little Kids First Big Books) is an excellent first book, but hopefully won’t be their last. The large color pictures and the interactive questions will appeal to the youngest readers. There are interesting facts including when it lived, what it ate and they are organized by size. I really like that they mention things that put more emphasis on the fact that all dinosaurs didn’t live at the same time, by sometimes making specific mention of contemporaries. I’m a little disconcerted at the size comparison to humans, which is ubiquitous in dinosaur books. It is a great comparison, but makes it difficult for young ones to understand that they didn’t coexist with humans. My 3-year-old keeps asking, “Is this one good to humans?” The information is broken up into chunks so that you can read as much or as little as you want on each page, depending on the attention span of your kid and how soon you want to go to bed. By the same token, it is not very in-depth, so older kids will want to move on to another book, after they have this one memorized. It is listed as being for 4-8 year olds, but I would say that the information is good for 3-6 year olds, though 6-8 year olds will enjoy reading it for themselves. The Dinosaur Guy recommends it!
