Query: Insightful, worthwhile read

I was given these books by a friend and am forever grateful. There is everything in there from the science of leaving a window slightly open in your home year round to effective toddler time suggestions. The reading is simple, but deep. I had to buy the hardcopy because I love to refer to them any time and place I need to, but the kindle edition is ok too. It's a long read, but worth every second.I do suggest you read other books based on these to simplify personal applications of these learning and parenting theories as well including the one below. They are short and easy to turn to quickly.When Children Love to Learn: A Practical Application of Charlotte Mason's Philosophy for Today
