We have only been pumping a month so I am still perfecting the correct amount of insulin to last 3 days as McKenna's insulin needs are changing because of school. Anyway, we changed McKenna's inset and insulin on Saturday so I was prepared to change it out on Tuesday afternoon before dinner. Well, yesterday McKenna comes home from school and says, "Mom, I only have 1 unit left in my pump." Well, we did a quick change because we had to get to tutoring, but that was a little too close for comfort. I added more insulin this time!
