Our target range is 100 to 110. Is my daughter's BG always between 100 and 110? Not by a longshot! But we keep on aiming for this range anyway. And we've been achieving BGs between 100 and 110 a whole lot more often with a great deal less effort since we switched to pumping (along with Dexcom, of course!). Pumping is definitely not easy, but it has gotten us quite a bit closer to tighter control.
