I know Darryl has an overwhelming belief that rebounds are a figment of my imagination, but in reality, they happen to quite a few Type 1's. Heck, he even explained away the one I caught on a CGM a few years ago. You believe what you see - and as Sugarmonkey said, and I have said, and one of the teens here has said, and a handful or two of others have said, reducing the insulin, after all other causes have been addressed, sometimes works. However, I don't think rebounds is the case with your child since her numbers are good at night. Look at how much you have increased her daytime basals - do you make tiny increase or are you more aggressive? Does her daytime basal seem to be extremely high when compared with her nighttime basal? Are corrections bringing her down into range? Is it the bolus? Is she about 80 points higher 2 hours after she eats? Or is she way higher then that? These are all things that I would answer first before I even considered thinking it was a rebound issue. In my mind, the only way you can tell 100% for sure that it is not a rebound phenom occurring is to test, test, test.
