All good stuff. Depending upon the vibe from them, I agree with Anna that maybe a quick safety review and touch/feel session at home before going to the range may be helpful since they've never held one before, just for comfort sake and so they don't get overwhelmed with everything going on at the range.
Also be sure to give them a good large silhouette target and keep it close to start. Putting holes in paper anywhere feels good. If they pick it up quickly, great - challenge them with a best of 5 shots or other ways to mix it up.
Don't one up them as was said - I accidently did that to my son last week. He was having difficulty sighting a new rifle last week that we had just picked up. Got a little frustrated and said he was done. I picked it up intending just to put a few down to see what the issue was. Well, it wasn't the rifle. He'll get over it, but isn't as excited to go back out with it again. No need for you to shoot really, but if you do, just remind them you've been doing this a long time and started out the same way.
I'm not dumb. I just have a command of thoroughly useless information.
