Sorry to hear about your grandson. Our 6 year old grand daughter was just diagnosed in August. It was quite a shock for all involved. Fortunately our granddaughter, her parents, and both sets of grandparents were required to attend about 14 hours of training, test blood glucose, count carbs, and administer insulin. It helped quite a bit ease the process and gave us some basic information and what to look for if she was “low”. We recently joined type one nation website and have found a lot of help.
One thing I would reiterate that others have said, keep a positive attitude and they are the same kid that that likes to play, laugh, and have fun!
