name Ekaterina? Bleh, that kid is going to get bullied xD
and Alexander is kind of old fashioned, and quite long, his friends will probably shorten into Alex or something liek taht xD
but wouldn't Nina be quite good for a girl and Niko for a boy
(
http://en.wikipedia.org/wiki/Niko actualy quite international)
Well, Those 2 you mention are quite decent names BUT bit too long as 1st name, at least I think so, and also I think that the names of Kids in the Family should sound good, soft, etc. when mentioned in same sentence.
Well, I allow myself to use my name as example,
1st name: Niko, easy & short name.
2nd name: Eero, another short and easy name (also bit older)
3rd name: Antero, Old, long, and strong.
Well, then the 1st name of my lil'bro is Jesse. So when spoken in Finnish; it is always Niko & Jesse (sound good because of the finnish pronouncion)
ANd well, a small list of my cousins (who live in the same household)
Hanna, Heidi, Tessa, Lotta. (all fit together at least with Finnish pronouncion)
ALso, I think that the 1st name should be that kind of name that isn't possible to shorten. So the child will always be called with his/her name. So that it wont shorten. ANd of course names are bent very often, but that is just because a loved child has many names.
