I love endo's... seriously The only target range that matters is what will keep the body healthy. The body has evolved over millions of years to tolerate the nondiabetic fasting BG's 70-99 and post-prandials of 140 for moderate carb intake (even chimpanzees share this nondiabetic glucose range). Anything over that is abnormal. So the question is what range you can achieve safely. I don't think a pink panther book (or an endo who reads the book) can tell you this. It is something you need to discover for yourself, it will vary from child to child, and also depends on what type of pump, BG monitoring, and insulin you use. It depends on the day as well - some days may accomodate different target ranges than others depending on exercise, growth patterns, etc.
