My younger son was diagnosed about a year ago with type 1 diabetes and he had just turned 2 yrs old. What the previous poster said is exactly right and in hindsight perhaps the extreme hunger would have been our first sign. He was actually eating (at age 26 months old) more food for breakfast than me, my husband and my older son put together

He could eat 2 poptarts and 2 bowls of cereal for breakfast and this was typical. He was always starving. He wasn't losing weight as many folks do but wasn't gaining either. Then in a couple of weeks he started the excessive drinking and peeing (into his diaper - he'd soak through a diaper in an hour or 2 and pee'd out of his diaper every night pretty much).
Our HMO"s policy, once I called them and told them his symptoms, was to see him within 24 hours and sooner if he seemed ill. Fortunately we went in the next day -and they told me they were almost positive he was a urinary tract infection and not diabetes as we were waiting for the results of his urine test. But of course he had diabetes - I pretty much had realized by that time that he was diabetic. We were very very fortunate that we caught it early and he actually wasn't very sick at all. I've talked to many parents however that didn't catch it (or the doctors misdiagnosed it!!!) and their children were practically in a coma by the time they were diagnosed.
I would suggest that you keep a close eye on him - if he seems ill at all take him to the ER or your dr's office if they will see him right away. Otherwise the Thurs. appt should be fine. The Children With Diabetes is a great website and resource. The URL for a list of symptoms they give is at:
http://www.childrenwithdiabetes.com/clinic/signs.htm Note that if your son has these symptoms: vomiting, lethargy, confusion, and flu-like symptoms those are the ones that are VERY serious and mean a trip to the ER right away.
Out of curiosity, why was he tested at age 5? And there is no reason to thing that your gestational diabetes would cause him to be diabetic although diabetes and auto-immune diseases can run in the family (I mean you could have passed along some genes to him but having the GD didn't give him diabetes).
The CWD site also has a chat room and you can go on there and talk to other parents and chat more about his symptoms - folks are very very helpful. Go to:

Sadly, I know so much crap about diabetes now my head could easily explode. Please feel free to pm me with any questions
