I think the problem lies deeper.
Less people knit, less people introduce their kids to crafts at home. Since they do get all the entertainment they can get outside home or within a screen ... why should anyone worry?
My mother taught me crochet when I was just 3, maybe 3 and a half. Shortly after I learned knitting from my grandmother.
But as the generations go less people learn knitting. That is why I think you should teach any interested person, no matter of what age and make them carry the virus of yarn work. It does spread again and the younger you are when you catch it, the better.
Oh, for teaching that kid: how about you let him in on the secret of online forums about knitting once he has mastered the beginning stages. He will come by patterns and ideas and bring them home.
A hat by the way for a guy.. how about the one by Jared Flood?
that might be a good second project after a plain color hat with a spiralling decrease...
