I think this is understandable. They sell pumps. They are not diabetes care specialists, and as sellers of pumps they wouldn’t want to get into teaching carb counting or figuring out carb ratios and so on.
You could teach yourself lots, but make sure your province’s involvement in paying for a pump and/or your workplace insurance don’t require training with a pump trainer and regular appointments with an endo or CDE. If I recall correctly, the Ontario ADP grant application form requires this.
Sounds like you’re pretty much up to speed, though, so any education/training would be a formality, and over pretty quickly. But they have to be able to say they did it.
I don’t know what province you’re in, but if it covers pumps and/or supplies, take their money first. Private insurance pump coverage can be quite limited, as in $5,000 over your lifetime. Buy one pump and that’s pretty much used up.
In the meantime, put in the batteries and play around with your PDM. Do as much of the set-up as you can at this point, get familiar with the features, and you’ll whiz through your training. Have fun!
