On an average day, before I was pregnant, I probably made one or two correction boluses a day. Like you, they mostly weren’t massive, just little tweaks to keep things on track. I don’t know what the official line is on correction boluses but I find them an essential part of getting good control.
I always think about why I’m making the correction – generally it’s because of a carb counting error or a change in my plans ie I’ve been more/less active than I’d intended. Anything more than that and I start looking at whether my basal rates or carb ratios might need a bit of tweaking.
