I don't see what the problem is with Borg kids. We saw Borg babies in the very first Borg episode.
I'm not disputing the existence of borg babies. I'm just saying that the borg kids in VOY were annoying. (I assume you were being sarcastic, but anyway)
However, I love how they velcro plastic "technology" to those babies in the TNG episode, stuffed them in a drawer and called them borg babies. Classic!
