Last night our DD had a super high number (489) 27 mmol. We did a +200% basal increase for one hour and she dropped to 288, 16 mmol in one hour. Another 2 hours later, she was (79) 4.4 mmol and we then gave her 4 carbs of juice. Anyway, to us, it seemed like we did the right thing and she came down nicely (a little too much, but trial and error, right). My question is whether it is "safe" to drop like that? I mean common sense tells me it is good to get her out of the high 400's quick, but is it harmful to drop BG so fast? Would it have been better to bring it down slower? Although I hate to see her ride that high, YKWIM. What do the experts here do? Thanks in advance.
