hey mark I know you posted this a long time ago but just wanted to let you know that when I first got on the pump I was pregnant. With nine months of skin stretching and getting thinner the best thing I found were the silhouettes. They go in at an angle and doesn't require as much fat. I never had any trouble wearing them on my prego belly. However once I went to the quick sets I was using what they call skin tac and that was so sticky it was causing my cannula to crinkly up and not even go under the skin. A hospital visit in a snow storm later I finally figured out what the problem was. Hope this helped.
