I haven't read each of these books, they come with link to Amazon so you can read others' reviews.
Plenty of books for everyone. Links to many books on the USA Amazon.com website recommended by the USA site CWD (Children with Diabetes). Some books are written by health care professionals, a couple from the UK, plenty of books are written by people with diabetes themselves, there is even a 'funny' book or two amongst them. There are a couple for starting school but be aware these are American books where schooling is slightly different.
