I love the IDEA of this book. However, in real life I've had some difficulty implementing the ideas. Frankly, sometimes I've also been left worrying terribly about how far behind my kids are if they can't yet name the items at age 52 weeks like the author says they might. Overall though it's a great Preschool program to follow, very clearly laid out, and progressive in developmental expectations. It is the Preschool guide to follow if you're following the Well Trained Mind.
