Ask his parents what he's interested in, then I would suggest something like the Dorling Kindserley "Eyewitness" books. ( They also used to have some of them in video ( VHS ) form, when my kids were younger; check to see if any might be available in a more current format. ) Music - good, happy music. Check out the Vince Guaraldi tunes for the old "Peanuts " animated specials. Very happy, very approachable - and appropriate for EVERYBODY.
