Definitely ask about a pump if you think it might help you. My daughter went on one 8 days after diagnosis so we definitely didn’t know anything about them, or much about diabetes, didn’t get the chance to run it just with saline in to practice, never did a DAFNE course (they don’t do them for children or their parents) and the only carb counting training we were given was half an hour with a dietician and a free copy of the Carbs and Cals book. Talk about being chucked in the deep end and see if you can swim! But we managed so I don’t see why other people can’t either.
To give you the full picture though, there was a trial just starting comparing pumps with MDI in newly diagnosed children and they desperately wanted participants (actually I think my daughter was the first one they signed up at that hospital), we were in and out of hospital a lot for the first few weeks duto being so newly diagnosed, and could contact the DSNs fairly easily in the meantime so we did get plenty of support. If we hadn’t been able to get used to the pump and understand it well enough then they wouldn’t have let us keep it!
