We have been trying to start the minimed pump on my daughter for the last two days, but each attempt has failed because of a bad site. She is 5 yo and very lean. Infusion sets tried and failed: Quick-set: tried in abdomen and then in fatty-ish part of buttock. didn't work. when I withdrew the cannulas, they were bent. Silhouette: tried with the sil-serter lying flat against skin. didn't work. cannula was bent when I removed the site. I think that I need to re-try with the silhouette, but holding the sil-serter so it inserts at a shallower angle. Has anyone had a similar experience? How shallow did you have to go to get the thing to work? Any advice welcome. So frustrating! We have spent weeks getting the kid excited about going on the pump, but all it has gotten her so far is 3 tries and 3 fails, with some nasty highs in the process. Tks.
