As much a manual for Catholic parenting as for homeschooling (and I'm not sure there's a huge difference between the two at the preschool level.)
Very useful for knowing which things to worry about and which ones are irrelevant.
The last section is mostly a plug for the Seton curriculum, but they are the big name in Catholic homeschooling, so I'm sure most people reading this book already have at least an initial impression of them already, so I didn't think that was too terrible.
But it's a quick read, and very inspirational coming from someone who homeschooled her 12 kids (yes, really!), and is now helping homeschool her grand-kids.
