After I delivered, they whisked my baby from the room. I barely got to see him. He was not premie, but i’m diabetic. Why did they do that?

Blood sugar. Infants of diabetic mothers need to be tested immediately for a drop in blood sugar, and sometimes get the glucose IV to prevent seizures and brain damage. Because they get excessive sugar from the placenta, they have very high levels of Insulin in their blood right after delivery.
