I'm type 1, and my son was 7lbs, 13oz. Not a HUGE baby, just a nice healthy weight. I did have a c-section but that was due to other issues besides my diabetes that if it hadn't occurred, my doctor was like there's no reason not to let you try to deliver vaginally. As far as weather you will be induced, I don't think anyone can say for certain, a lot of pregnancies go wonderfully for women diabetic and non-diabetic and something comes up in the last few weeks and it changes things where induction or c-section is necessary. The best way to have a healthy sized baby is to keep your blood glucose levels under tight control. But that is a goal you should be striving for anyway. As far as eating, the baby will take everything it needs from you, so especially being on insulin you may find you need to eat more frequently, and definately test a LOT. Eat when you are hungry, watch the carbs, I'd personally say moderate carbs if possible because you have a baby who is needing the nutrion as well.
