If you only buy one reference book to help you manage your child's type 1 diabetes, buy this one. It is thorough and authoritative, easy for the layman to understand, and considerate of its readership. The author is clearly a humane and caring medical expert who cares deeply not only about his patients' physical well-being but about their emotions too. My daughter, now 9, was diagnosed at the age of 3, and I wish I'd had this book from the beginning of our journey. With Dr Hanas on side, I feel so much better equipped. I reckon in any medical crisis, knowledge is power, and this book is very empowering indeed.
