I get your angst and can understand how previous losses would play into the emotions of it all. 4.7 is perfectly safe on either meter. If he goes below 3.8 then you boost his BG with HC and keep him up. Even that number has a bit of safety built in. On the human meter 2.8 would be the point where high carb comes into play. It's just that we don't want to necessarily push them down that far that we make dose adjustments at 5 (90) at least this early in the game. As time goes on and you understand Stan's reactions more, then you could reduce at slightly lower levels. So tonight, take him down to 1.5u and let's see what he can do with the new dose in the next few days. He's doing so well you should be proud of yourself. You got this and Stan's a lucky little fella!
