We're having a lot of issues with the pump right now. It's been really frustrating and I'm thinking about going back to mdi for my dd. Problems are blood in cannula, air bubbles in tubing and reservoir causing her to not get insulin, had to replace pump once already under warranty for not delivering insulin, stuff like that. It's only been almost 3 months since she's been pumping but these problems don't seem like the type that would just go away. What I want to know is if anyone has been so excited to get the pump, and then be disappointed to the point of going back to syringes. I'm seriously considering it because it's been problem after problem. I'm going to try one last infusion set and if that doesn't correct the blood in cannula, I think that will be it for us. I really thought it would make things better for my daughter, but it honestly hasn't seemed to do much, except we can fine tune her basals overnight. If you have gone back to mdi, how was the adjustment? Do you regret it? What were the reasons you went back to mdi in the first place?
