Hi, we are still fairly new to all this, diagnosed in January, started pumping in August, managed to get a Dex later this week. Whew, been a learning year! So, with the Dex....what do I need to know? Any suggestions are greatly appreciated. Just a little background, my ds is 10 1/2 and is learning to do well w/ carb counting and putting everything in the pump. We did a 3 day trial w/ DexCom, per insurance and he liked being able to look at the screen and see where he is, w/out finger poking. Although we found the Dex and the finger could be off 20-50 points either direction. I'm guessing we will learn when we can trust the DexCom and when we can't. I've seen a thread about no Tylenol, throws readings off. Did I imagine that? What other little things have you learned that you can pass along?! THANKS!!
