JenP how will you know unless you read it?  In my opinion it is an excellent source of reference, it is written so we can understand it. It has also been checked and co written by an excellent Professor of endocrinology, Dr Rivkees, that cared enough about both parents and suffers to give his time along with Carol M to make sure it is easy to comprehend and help.  On line, it is all about how one interprets things and not everyone’s problems are the same.  I am sure if such a distinguished Professor, such as the late Dr Crawford recommends this book to both paediatricians and parents, there will be something you or your child can gain from having a copy.  I thought I was knowledgeable regarding CAH until reading this book, now I realise how little I really did know and understand.
