Hello Long time poster/T1 from teens but an adult. I have used Medtronics pump and cgms for years, pump for many years. I just got in the mail my Tandem X2 pump...Slowly learning how to use this new pump It is so interesting how automated my habits are after what is maybe 20 years of pump use with one brand. So I am slowly working through the set up. I use so many short cuts and ignore so much on my Medtronic that I am anxious to get to that point with my Tandem.I am still using my Medtronic pump and CGMS and will switch when I get my Dexcom supplies, but am programing my pump. Anywho, as someone really in the habit of one system I will be reaching out to you experienced parents for any glitches I experience.
