Hi. My son just started on the minimed revel 523 Wednesday. So far it seems to be working well although we are still tweaking the numbers. He is almost 9 and loves it which is great. The biggest problem we are having is that he consistently complains the site is hurting him. We are using the Sure T. He always wants it on his stomach (the 5 times we've now changed it) which seems tender. I talked him into trying it closer to his backside, but of course now his pants are rubbing on it. We are also having trouble with the adhesive on his skin. It leaves it bright red and rashy. He's pretty skinny and has really fair skin. Any tips on where to put it and how to do this more smoothly resulting in less discomfort would be great.
