"Fey" Changlings?

[MaxKaladin]

I'm putting together a vaguely Celtic campaign for my group and I'd like to include some kind of "changeling". In legend, these were fey babies who were substituted for human babies. I'm not looking to make them evil in any way, just "odd" or "differerent". Are there any good sources I might check for races or templates that might fit with my idea?

Thanks!

There's a Half-Fey template in the Fiend Folio (I think) that would probably do excellently for a fey changeling. That's all I can think of right off-hand...

make them some type of fey, with the additional ability to appear human-ish maybe?
