Now I am wondering if we have a bounce tonight, she wasn't low when I went to sleep, but I gave her a spoon of gravy with her pre-sleep meal because she'd dropped 30 points (US) from +2 to +3, and she ate again at +5, but the high numbers today make me wonder.
If she bounces it is usually quite short, so will see just now, I will feed at +4 (on schedule) and test at +5.
