My mom never mentioned it until I had my own child (or maybe I just never paid attention), but my neighbors growing up wrote this book. It's pretty great. The first bit of the book goes over their parenting philosophy, which is basically to foster independent, creative, respectful, and inquisitive children. Most of the rest of the book is dedicated to ideas for projects, science expiriments, and etc. Violet is way too young for most of this, but I definitely will come back to the book as she gets older. Conveniently, they break down nearly everything by age.
