My children don't have diabetes yet, I say yet as in my family my parents, grandparents, aunts, uncles, great grandparents, great aunts and great uncles and all my siblings and all their children are diabetic. Yes - all of them!
Only a few are obese the majority of us are not overweight, I thought I had escaped the "curse" by watching my weight and eating a very-low fat vegetarian diet for my entire life (oh how little I knew then!) but I had gestational diabetes that didn't go away after I had my youngest.
So I added to the family statistics of 100% T2's
I control mine by a low carb high/healthy fats vegetarian diet and no medication.
