I’d suggest checking out your local library, because I agree, one reads a book once and seldom goes back to it. If you find that you want to continue checking out the same reference book over and over, then you’ll know you have found what you are looking for.
We have Pumping Insulin and Diabetes for Canadians for Dummies and of course the books that came from Medtronic with David’s pump. We bought Calorie King’s pocket size Calorie Fat & Carbohydrate Counter that I carry around in my purse, but David has had to become adept and estimating carbs as Mom is not always with him when he eats these days.
I am probably overdue to re-read what we already have as some of the information can probably be better grasped now that David has been pumping for the past two years. I recall my initial read through a somewhat overwhelming and David has yet to try the dual wave or square wave bolus features of his pump.
