Our DD has had Type 1 for more than six plus years and though we do have days where she no higher than 200, with no lows they are rare. I think you hit the nail on the head when you specify those diagnosed as children because I believe LADA has a longer, slower, gentler progression, although it is still Type 1. I, too, would love for her to be able to stay within those ranges, but it is unrealistic and not possible. We test often and treat the highs immediately; as well as the lows. As far as "pattern" is concerned, there is a pattern of sorts. But within this pattern, there are basal adjustments almost every day, either up .50 or down .50. I call this "tweaking." She also has subpatterns, where sometimes she has dawn phenom and sometimes not. As long as there are no major adjustments, such as during puberty, the rise and fall in basals will become evident and we will tweak up or down. It is more difficult when a major increase is called for in the evening hours because it will not last and there will be lows. We have a somewhat stable period (when whatever the basal is, it will stay within that range) from 1:30am thru 4pm. In that stable period there can be the Dawn phenom rise from 2 to 6am (or not) and a possible drop from 2pm to 4pm (or not). I guess what I'm getting at is that there are two or three familiar basal pattern subsets that overlay the basic basal pattern. You kind of intuitively know when she goes high at 2am, to apply more basal because tonight she is having dawn phenom, etc. Once that happens it tends to occur two or three days in a row. Constantly moving target but if you keep a written log, I think you may be able to identify your own patterns and I believe they will be multiple. In short, if you are willing to wear a cgms, that would be your best bet because you can then proactively manage your blood sugars. Type 1 is diabetes mel., uncontrollable. And I believe it is exactly that, uncontrollable swings in blood sugar that can be managed. Not controlled. The younger the age of diagnosis, I believe, the more severe. This does not mean you cannot have good A1cs, by the way. But on a cgms, your graphs most likely will never be flat.
