I didn't realize that Neelix and Kes's relationship could be seen as unseemly until sometime after the whole series was done, and I could see that Kes was really a child when Neelix met her.
Kes was as young adult by Ocampan standards. Yes there was a wide range in age/experience between her and Neelix which is why the relationship didn't last but Kes was not a child.
Not a childs body, but a childs mind when Neelix did meet her.
