I have been using Katie's products and ideas from her blog for months now, and when she told us about this release I knew the quality it would contain and pre-ordered immediately. It did not disappoint. My 3 boys (ages 3-8) love learning about tons of different interesting facts in a way that makes sense to them. The graphics are very well done. My 8 year old says "You should get this book because it tells you a lot about your body and it has some fun games". Each of the 16 sections covered has pages of facts following by activity page(s) and hands-on "try this at home" to reinforce the content. The end includes both an excellent 2 page resource list, and an index containing over 140 different items (in a 68 page book!). Money well spent!
