I had all the reps from the different pump companies come out to our house and my 10-year-old was involved in all the meetings. The reps were great, and let her ask questions, touch and feel the pumps and infusion sets, etc. She was nervous when it came time to do the first infusion set, but it wasn't nearly as uncomfortable as she thought it would be. We made the deal that we would try the pump and if she didn't like it, we'd go back to MDI, I wasn't going to force her to do anything she didn't want to in terms of her diabetes management.
It's been about 10 months, and I don't think she would trade her pump for shots at all. She loves the flexibility the pump gives her in terms of being able to eat a little now and a little later. She loves that she can do special features to help with foods like pizza and pasta, and she loves that she can easily keep track of whether she took her insulin or how much insulin she has on board. It has freed her up from having to go to the school nurse every day for a lunch shot, or me having to accompany her class on field trips to give her a shot (I still try to go if I can, but there is always someone diabetic trained on the field trip). She is much more in control of her own diabetes with the pump and it gives her a lot more freedom.
Going to diabetes camp last summer and seeing all the kids with pumps also gave her more confidence to try it. And seeing that just because she was wearing the pump, didn't mean anyone else could see it, she keeps it in her pocket or on a belt under her shirt, and no one knows the difference.
