Well, I’m back from my meeting with my DSN, and, wonder of wonders, the regional pump specialist nurse was also there (I dont know what her official title is, but educator should come into it somewhere…). Each time I said ‘Well I find that…’ and my DSN said ‘Oh, that shouldn’t happen, should it?’ (or words along those lines), the pump nurse said ‘Oh right, well some people find that…’ or ‘Yes, I’ve come across that…’ So I got reassurance that I am working along the right lines, and my DSN has some valuable new knowledge. I now just need to work out the numbers more precisely than ‘try 1:12 and see how it works’.
(They both agreed that mine was a particularly complex case to sort out. Which, oddly, makes me feel better.)
