I've been off this board for a long time but I'm having a lot of difficulty with basal rates and I know this crowd has great expertise so here goes: My daughter is 11, has had type 1 for 7.5 years, and has been pumping for four years (I think). Over the past 2 years we have had a lot of site problems. Some sites have great absorption and some sites have terrible absorption. I have tried to solve the problem by creating three different basal programs: 1 for great absorption, 1 for terrible absorption, and one for something in-between. The problem is that it takes about a day to figure out which one it is. Often more if her activity level changes from the first day to the second (she is very sensitive to activity). As a result, her basals are all messed up because I don't know if her bad blood sugars are due to a mismatch between the site and the basal program or some other factor (usually activity level). Even when I do make changes, I don't know if they work because a day later we have a new site. It is very frustrating and her numbers are everywhere. Six months ago her A1C was 6.9--amazing for us (we give her a lot of freedom which means we have to accept a higher A1C, so we were not expecting to see her below 7.0 until she was much older). Last month it was 7.7. Not awful, but not where we want to stay. But my problem is not really about lowering her A1C. It's more about how to methodically work through these three basal programs to get each one of them in better shape for her. For example, should I make it a rule to always fine-tune after day one, at least a little? Should I get rid of these programs and try to keep just one basal program but really work with temp basals? Should I insist that we try new sites which will almost certainly be good sites so that we don't have this variability (new sites flip her out)? I'm looking forward to your insights. Thanks in advance.
