The device Tonya is talking about is a insulin pump.
I'd wait to use a pump until you know more about your daughter's metabolic needs. The pump that leads the market is the Medtronic MiniMed, but there are other pumps that are much more kid friendly, so work with your Pediatric Endocrinologist and CDE's (Certified Diabetes Educators) to make sure you have it as fine-tuned as possible.
Type 1 diabetes isn't a death sentence. I sold insulin for 4 years and worked for another diabetes company for another 4 years. I know many people and have many friends with type 1 diabetes that were diagnosed as young children, and all are doing really well today.
There are many different kinds of insulin on the market that are available. Though they should all work the same, each patient will react differently, so don't be afraid to ask for Humalog vs. NovoLog vs. Apidra, Lantus vs. Levemir.
As far as meals go, it will take a little time to get accustomed to how carbs will affect her blood sugars. But, there's nothing someone with diabetes can't eat - it's just a matter of learning how to match the insulin with the carb load.
I'd recommend visiting the following websites and getting involved in patient support programs - often they have CDEs on staff (most of whom have type 1 diabetes) to help support your family through this journey:
