It depends on how she looks re likelihood of throwing up and interest in eating vs whatever she's doing (there are some well-established signs with her of each), but also I haven't seen a pattern yet in the drops. Sometimes a mid-morning small meal/snack does something, other times it doesn't. Sometimes without a snack between AM meal and +3 BG the drop is only down 20 points, sometimes it drops 200 from around the same starting point. There are treats at every BG, but whether there will be 1, 2, or 3 small meals between AM/PM regular meals depends on how she's acting. She was obese before diabetes, so I'm also being careful to keep her in a good calorie/weight range.
If feeding her again before +3 is something I should be doing regularly I would need to cut her AM meal in half to prevent vomiting. Which I could do. I went up to the slightly bigger breakfast and dinner (about 1.8 ounces) because when I was doing the small ones (more like .9 ounces) that I used to do when I was feeding like 6 baby meals per day, it seemed like she would drop too fast and too low, so I wanted to get a little more food in her before the insulin. To prevent the vomit train, giving her a couple of small meals before PM works best around +4 and +8, but if she looks iffy at +4 I'll hold off until +6.
But I'm open to suggestion!
