I have a type 1 diabetic daughter, she was diagnosed at 2 years old (now 24). It's a difficult thing to deal with. I don't know where you are based but, in Scotland where I am, if we have any problems we can contact the Diabetic Liaison nurse at the clinic she attends. These nurses have always been available to advise us with any problems. Failing that and you need advice in a hurry, try the diabetic ward at the hospital you attend, and ask to speak to the Diabetic Registrar on duty and they ought to either take your call or else get back to you, they're usually pretty quick here. Your son's denying his need to go pee could be related to something other than his diabetes, his trouble may be something else. I think your best bet is to get in touch with your own doctor or if it's an emergency call NHS 24 for their advice. It can be hard at times dealing with a child with diabetes especially when they are so young, so if you need any help in the future please just post a message and I'll try to help, as will others on AB. I've been there with a diabetic child so I know what you are feeling and what might still be ahead.
