content: So I feel weird about this book. I am down with Montessori "schooling", but this book didn't give me anything new, in fact most of it was pretty dated. And much of the theory was very common sense, such as how to show your child how to do something, I was like "um...yeah, no kidding". Also, I don't know if this is because it is so dated(40's?) but many of the tasks for "3 to 5" year olds my 1 1/2 year old can do, or is already learning, I felt like much of the things this book guides you to show your two year old, my bobbler already gets. There is even a part where it suggests we start teaching colors at age 3, my kid knows all his colors even though he can't say them. I am not bragging here, it was just weird. Also the "busy board" is put together with upholstery tacks, and I am pretty sure I wouldn't want my kid playing with something that included tacks.There was NOTHING here that I couldn't find on Montessori sites, or mom blogs.
