I know that it might not seem so right now, but this too shall pass in time.
Being firm as a parent is important. You can say, "I know it's not fair, and I know it's not fun, but we have to do this now so that you will be healthy and feel good."
You might want to consider attending a local support group, so that your son can meet other kids and adults with type 1. He'll see that he's not the only one, and that can be a big help.
CWD's conferences offer the same opportunity. We have one in Marco Island in January (see http://www.childrenwithdiabetes.com/...ies/Marco2009/) if you are able to fit that into your schedule.
