We use the T-Slim and like the extended bolus feature. However, sometimes (not often) during the hours after a first meal my kid will want to eat a second meal and the second meal will also best be dosed with a second extended bolus. The pump does not allow a second extended bolus. Is there a way to cancel the first and create a second one that will take into account what was supposed to happen with the first? For example, suppose my kid eats some pizza and doses for it with an extended bolus then three hours later wants a second serving of leftover pizza. How would one best dose for the second serving?
