Training other care providers on how to use pump

My son's green Ping will be delivered on Monday, and it will be 1-2 weeks before we actually have pump start, but I am a little nervous about training our daycare provider, my son's grandparents, etc. on how to use the pump when they care for him. Is it hard? I am most worried about my mother in law who is not computer literate. She is great about calculating doses and giving shots, but I am just worried she will be freaked by having do everything from a machine. I know we'll figure it out, but any insights from those who have gone before are appreciated!
