Plot hole: In this episode Kes states that she has to decide now whether to have a child or not because Ocampa women can only get pregnant once and deliver one child. If that was the case they would have died out a long time ago, or never even evolved, as two people only getting one offspring would reduce the population to 50% of the original figure each generation.
Basics (1) - S2-E26
Plot hole: The Voyager was continuously attacked by small Kazon attack ships. Yet the Captain never orders to increase the warp speed to evade them (In previous episodes we saw that the Voyager has much higher max speed than any ship in the Kazon arsenal). They simply travel at a lousy Warp 2 and wait to be attacked. It would make sense to travel slowly if they were trying to avoid being detected by Kazon but that was not the case. They were attacked constantly. Voyager may be more maneuverable at slower speeds but if you can outrun your pursuers there is no need to maneuver to avoid them. Also, if Voyager was traveling at a higher Warp Speed, there would be no way for the Kazon to array fighter craft ahead of Voyager as they would not be able to overtake Voyager. If they could, there would be no reason to deploy the fighter ships, they could simply engage with their capital ships.
Continuity mistake: When Samantha is holding her baby while the captain talks to her, her hands are apart with her right hand under the baby. In the next shot, her right hand is on top of her left hand and not under the baby.
Character mistake: As Voyager is bombarded by the cyclone, Paris reports that Voyager is at 20,000 meters and falling. 28 seconds later, he reports that Voyager is at 18,000 meters and states that, at this rate, they will crash in 10 minutes. However, if they drop 2000 meters in 28 seconds, they would actually crash in 252 seconds (just over 4 minutes). One might argue that perhaps it was calculated that their descent would slow down as they approached the surface, but later they fall from 2000 meters to 1000 meters in 14 seconds - the same rate.
Revealing mistake: When Kes is eating the spawn beetles, the same shot is used twice for when she scoops out beetles from the tray. The untouched beetles are all in the same place, and there is a beetle that is nearly flipped by her thumb both times.
Projections - S2-E3
Other mistake: At the beginning of the episode, as B'Elanna is working her way out through the doors, the Doctor cowers and tries to hide behind things. There is no reason for him to be afraid. He can't be hurt under normal conditions - this proves to be the case later when he feels pain and says he is not programmed to feel pain, and we learned earlier in "Phage" that he can change whether or not things pass through him.
Continuity mistake: When Torres and Paris enter engineering, the warp core is dark showing that it is offline. Minutes later, it is illuminated and online. (00:19:15 - 00:28:30)
Resistance - S2-E12
Continuity mistake: When Caylem dies in his close up shot, his head falls to his right shoulder, but in the next shot showing Captain Janeway holding him in her arms, his head is angled to his left (away from the camera).
Parturition - S2-E7
Revealing mistake: On the bridge, as Tuvok monitors and reports on the pursuing ship's weapons, you can see what looks like a wristwatch on his right wrist as he works the controls. (00:35:35)
Dreadnought - S2-E17
Continuity mistake: Dreadnought states there are fifteen priority targets approaching. On radar sixteen Rakosan ships are displayed. Then just before the Dreadnought attacks (and destroys three of) the approaching ships, there are a total of nineteen Rakosan ships displayed on radar.
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.
