Handsome boy.

Personally, I prefer to make light of a disability with a funny name that makes people smile and thus project positive vibes when meeting him. For the "ee" names, Skippy, Tippy, Gimpy, for a geek perhaps MP3 (Mouser Patrol 3), or TLC (three legged cat).

For a math fan, could call him Isosceles since his legs make a triangle, still a bit "ee" sounding.
Or if you are a Lord of the Rings fan, Legoless.
Edit: Oops, I missed the post that you already decided.
