I have a now 16 year old cousin who has had diabetes since she was 2, and she's been wearing a pump for a long time with good results. My understanding is that it helps keep insulin steadier than injections. Until she was probably 12 she would consult with her parents about what number to put in, like "did you have 2 pieces of pizza, and milk? That's ______" or whatever. I often wondered what she did when she was away from them. When I would babysit her, we would call her parents to ask what number to use, though I suppose I could have learned the formula easily enough. The only problem I really remember her having is once when she went swimming with some friends, disconnected her pump, and forgot to hook it back up for hours and hours. And of course the other kids parents were clueless, and her parents were pretty upset. I would think that if there is a real nurse at your daughter's school who knows what she's doing and that your daughter's teachers and anyone else who cares for her knows what to do with the pump and if you teach your daughter how to care for it, she should be OK. It may be one of those things where you go in and talk to her whole class and explain what it is to all of the kids so that they all know not to touch it or pull on her, etc. Your daughter will have to wear it on her pants, basically, all the time, so think about whether or not she could handle that. Good luck.
