Sorry to hear about your child and his child diabetic condition. I am an Sri Lankan Ayurvedic and TCM Therapist. I would like to give you hope from the point of view of traditional medicine.
Ayurveda does not see child diabetic in the same was the Western medicine sees it. Even though it is a type 1, it has completely different causes in children. and can be healed completely (if there is no family history of kidney and pancreas disease). Children get this illness due to lack of vasoprsin hormone secretion to stimulate the insulin production. hormones balance and the pancreas and spleen functions can be rehealed by the use of 6 herbs, and some dietary regulation. hope this gives you hope. So dont give up hope ....on your child......
