My son is very hypo-aware, so that he can often sense when he is coming down, even if his reading is still in range. Generally at home I assess how badly he is feeling and decide how much rapid kind of carbs he needs, like juice or dex 4 tabs or whether he can have a little more sustaining carbs like whole wheat crackers, etc. But today I got a call from the school saying that he was at 4.4 (79 in mg) and feeling low. We treat lows at 4.0 so he was on the edge. The thing is, he had 3 hours left of school, so if I advise to treat with juice, I'm afraid that this will not sustain him for another 3 hours. If I advise a granola bar (lower glycemic), I think this will last longer in his system, but maybe not bring him up quick enough if falling rapidly. I did advise the granola bar, but now I'm super worried I made a mistake and should have said to give him juice. I'm going to call the school again to check in anyway, but what would you all do?
