I have a number a great people in my life who are helping us as we stumble along the learning curve of diabetes with our 4th grade son. He spent a good chunk of his first year honeymooning (to the point of not needing insulin at one point). That has ended in a big way, and we are trying to learn as much as possible. For the first year, we pretty much just did what the sheet (see link) our doctor gave us told us (calling in to him for adjustments to the sheet from time to time). I have gone to the friends for advice and it seems that the message is to: 1) read up --- don't just listen to the doctor 2) figure out how your child responds to different foods and other variables 3) adjust accordingly I get the impression that #2 and #3 above are generally meant to be observational -- staying observant, looking for trends, and combining that with what you learn in #1. I get that. But at the same time, I'd like to do a few more "controlled" experiments. I figure a lot of you have tried little controlled (as much as you can "control" variables) experiments over the years, such as: ---- giving different foods and tracking blood glucose ---- exercising in different amounts and tracking blood glucose ---- testing more often to see what happens during sleep and other times of the day that you weren't sure about I assume the easy thing to tell me is: "Go out, give him some food he likes and see what happens!" Yet I am wondering if any of you have tried this type of thing in a more systematic way. I thought that, perhaps, there is an optimal time to do this, optimal starting blood glucose number, optimal time to track (and time periods between checks), etc. As much as someone can offer a "plan" for an experiment given the crazy nature of diabetes, I am looking for one. I am also looking for someone to lay down a few tips for what they feel every parent should know. My neophyte knowledge of this suggests that I would want to find out: 1) How much does 1 gram of carb affect my son? 2) How do different foods affect him differently? -- which ones hit immediately, and which ones hit later? 3) How long does his insulin last? 4) How does he respond differently to insulin and food at different times of the day? 5) How does rest affect him? Exercise? Stress? Sickness? I can't stress enough that I totally realize that things vary from day to day, week to week, and month to month. I also realize that there is never just one factor/variable affecting his blood glucose reading (might be sick, stressed, and just ate a fatty meal, etc. etc. etc.). But I think I'd feel a bit empowered if I had a little "cheat sheet" of tests that I could run him through every so often to see how different things are affecting him. Has anyone done something like this? I'd love to hear how you do it, at what intervals, and any other tips you might have.
