I am finding the past few days I have been having to give a correction three hours after eating, and it's been stubborn! As we all know, we usually never know why things change (all the TIME!), but I am wondering if it is time to adjust her IC ratios. Again. Those of you with 4-5 year olds, what IC ratios do you use? Oh, she weighs 38 lbs, in case that matters. I wanted to add that I do not suspect a basal issue because after she spikes, she holds very steady until the next meal time.
