[quote=kimck] My DS7 would LOVE to learn guitar.
Get a cheap little kid's guitar; could be acoustic altho electric is easier for beginners. Tune it to "open tuning". Have kiddo strum along with songs that he likes in open tuning. He can barre across frets to try to noodle along with the tune. The MAIN focus should be the timing and the rhythm. From there you can switch to standard tuning and work on chords and simple riffs.
Timing and rhythm is everything in the beginning. IMO if you don't get it early on - very early on, you'll never get it.
Remember to tune the guitar frequently to encourage the beginner's ear to stay tight - to be discriminating and critical.
Well, that's how DS learned when he was 6-ish anyway.
