I am diabetic. If my blood sugar is high, will my milk have too much sugar?

Your blood sugar level is unlikely to affect the amount of sugar in your milk. You body produces the main sugar in your milk in the breast and will keep that amount fairly constant (regardless of the level of glucose in your blood). In fact, breastfeeding may lower your blood sugar level as compared to before you started breastfeeding. Also, it was found that breastfeeding may help decrease the chances of the child developing diabetes.
