That old medical adage was once again proven true today. Ds10 has been having highs in the mornings post breakfast. I figured it was what he was eating and started experimenting with different extended boluses. Nothing was working and he was still high at 9am check. I'd upped basal a bit, tweaked the extended boluses, done all the creative things I could think of. And then I adjusted his insulin to carb breakfast ratio. And that fixed it. A beautiful 106 post breakfast today. I feel like an idiot. Why didn't I just do that first???
