what if the kid won't live in Canada?
people have some weird names and are asked to spell them all the time... not only foreigners... how many spellings can there be of one name? many.
If you get your name spelt wrong on a daily basis (I do) its frustrating....Alexandra is the Western spelling..so why not make the kids life easy and spell it that way if they are going to live in a none slavic country...As for how many ways:
My name is Shelley, here are a few that people have come up with over the years!
Shelley (perfect 10/10)
Sheila (yeah, I think some people are deaf!)
Chelley (this was the most recent)
