Other mistake: On the planet, as the camera looks at the Harojan from behind, the zipper for his costume is visible.

Other mistake: In the 3D cinema scenes in the Holodeck, Tom Paris and B'Elanna Torres can be seen using blue/cyan anaglyph glasses and the movie screen can be seen to be in blue/cyan also. This is fine and to be expected. However the shot in which the projection room can be seen behind the couple show the projection is through magenta/green filters. (00:03:30)
Suggested correction: It's also possible that it's simply required of Ocampan women to give birth the first time they go through it, and can then experience it again.

Nothing in the dialogue suggest Ocampa's can have additional children. While we can speculate about fictitious species, it's still a plot hole due to writing. Kes states she's going through the "elogium" which is a time of change where her body prepares for fertilization. She then explicit states the "elogium" only occurs once. While the doctor compares it to puberty, the elogium is both sexual maturity and "heat", that is, the time a female is ready for fertilization.

But it doesn't ever state the normalcy of birthing for Ocompans. Perhaps sextuplets is the norm?
Kes frequently used the word "child." If it was normal to give birth to more than one, she would know this and should say "children."

Do not forget that this is all done through the universal translator. For all you know the Ocompan word for child and children is the same so the translator cannot tell the difference.
