Michelle, it makes a lot of sense what your endocrinologist says about being concerned what the body does in a normal situation rather than in an extreme one.

And about the weight issue: I have mentioned this a few times in various threads on BB: My nan gave birth to 6 babies. All over 5kg (over 11lb). All were born at home with only a midwife present. They were all healthy and 5 of them still are (now in their 50s and 70s). Her first born unfortunately died when he was around 12 months of pneumonia.
Did she have GD? Who knows, they didn't check for these things. I doubt it as she had easy pregnancies and births. Some babies are just big.

Thanks for the link Michael.
