Here's a question for you, how often do you have to change them? My SIL (who is also a Type 1) and I were talking about infusion sets. She uses minimed pump. She mentioned that when she tried the steel sets that she had to change them every day. If you or your child uses steel sets do you change them every day. She said if she tries to leave them in for 2-3 days the site gets all red and filled with pus. I'm wondering if she's just allergic/sensative to the steel sets. Obviously because of this she doesn't use those sets any more. Just curious, since we were given some contact detach sets to try on Ashleigh. I doubt she'd want to use them if she'd have to change them every day.
