Actually, @Sam, your post is a perfect illustration of what I wrote about earlier:
You are totally discounting my son’s experience (and mine), and assuming that his physiology works like yours. It does not:
we tried returning to MDI twice and found out it made things worse, not better
we were able to prove that the problem was not the pump, but the changes due to the beginning of the school year, with several different sports, lots of extracurriculars, and schedules that changed every day.
as a corroboration, when we went on vacation, all of our difficulties went away (except for his bad peaks)
I am noticing that your other comment on this thread also totally discounts my son’s experience, and assumes that you know better:
In our case, this is total nonsense. I am being very clear, at the risk of being a bit rude, instead of being my normal diplomatic self, because I would be worried that people reading this thread could actually believe what you write. It may possibly apply to some people, but it certainly does not apply to many I know. I also want to be very clear because this kind of dismissive post almost stopped my son from posting on this forum, and I don’t want this to happen. He needs to read input from his peers, but he does not need dismissive or supercilious comments.
