I would call and ask the mother if he has voiced any
wants or needs. Depending on that answer, nerf toys
are a hit with active ones *beware: even parents are
targets* and giftcards are good. Teaches them monetary
value, limit to what they can afford to buy. And deciding
what they want more than the other. Renting games also gives
choices of playing as opposed to buying one game and tiring of it.
