At supper last night, Caleb's bg was 313, so with a correction and carbs, he should have gotten 4u of Humalog. I did the 2u dial-up and test shot, and then ended up not dialing back up to 4u and instead gave him an air shot. It wasn't until I checked his bg 2 hours later for bedtime that I realized my mistake. His bg was 469. So I gave him a 3u correction (which I rarely do at night because he tends to drop fast) and this morning he was at 47. It's just been one thing after another lately with his D. The week before last we were dealing with highs, now it's the lows again. Go figure.
