I managed to get my 8 year old daughter on a pump 1 month after she was diagnosed, thus she knows no other world. Her father, on the other hand, has had T1D fo 38 years and is still on injections, also doesn't want something attached to him all the time. My daughter's pump has failed a few times and during those days, she is not happy about taking shots. On the other hand, when we're changing infusion sites and she's off the pump for a few hours sometimes, she'll joyfully proclaim "I'm pump free!" I'm a huge advocate of the pump simply because when she was diagnosed at age 6, there's no way she would have had such freedom without the pump. I gave her a cell phone and when she wants to eat something, she just calls and we guess together how many carbs it is. Without the pump, she would have had many food restrictions that she never had. But it will be interesting to hear her opinon when she's your age.
So I believe that not only is there is no "right" answer for everyone, and even an individual's "answer" may change at different times in that person's life. When my daughter is in a bikini on the beach at age 16, she may very well not want a pump! It's a personal decison and there are pros and cons to both methods.
