As a health care professional and a diabetic for 27 years, I think I may be able to clarify what the educator was trying to say. Pumping is not easy. I went from standard therapy to multiple injection therapy to pumping over the course of 11 years because I transitioned as those therapies became available. Slowly, I learned about carb counting, how my body specifically reacted to different foods and different activities, and how to correct for highs. I was one of the first adolescents to be started on a pump (at the time they did not think teenagers could handle pumping). Now that pumping is available for everyone, I think some providers are concerned that newly diagnosed diabetics are not getting the training that I got over 11 years to prepare me for the pump. The work that she is talking about is important. It will mean that your son will live a long and healthy life. It also means that you and your son will have to work as a team to figure out what works best for him.
Whether the doctors are "good" or not, I think there are a few important things you should bring up in your conversation with them. First, research the benefits of pump therapy (there are many), and discuss with the doctor that you want those benefits for your son. Second, work with the educator to count carbohydrates, test throughout the day (not just at meals), and keep careful track of food, activity, and insulin use. This will show the doctor that you are serious about maintaining control and will do everything that it takes to make pumping worth your time and his. Third, see if the educator knows of some kids near your child's age that are pumping now. Many parents are willing to share their experiences (good and bad) with the pump, and they will be able to give you advice. You may also find parents whose children go to the same endocrinologist, and you can talk to them about how they started the pump conversation.
Both as a health care professional and as a person who has had diabetes and a pump for many, many years, I highly recommend that you do everything you can to get your child on the pump. Armed with some good information about pumping, I think you will be able to convince any doctor that pumping is best for your son. Good luck.
