No, I said it was insane to think that she was older than a year in Caretaker, and that was much later than the op. The nine month mentioning was from measuring by thumb after believing that anything that happened in season 2 happened in 2372, that and I haven't watched Elogium in years and I remembered the quote a slight bit differently.. But it is still possible. But the post most hinged oin the claims that kes was two in caretaker, which is clearly insane.And anyways What's wrong with being insane?
You said Kes was "assuredly less than one in Caretaker," and in the OP you said she met the VOY crew when she was 9 months. She met the VOY crew in Caretaker, and 9 months was your reference.
Above you changed to "less than two," and I would point out that "assuredly less than one" and "less than two" are not the same. So by your own reckoning, someone thinking that would be insane.
Using Memory Alpha's figures leaves my equation in good stead: Kes turns two in 2371, plus 7 years of show seasons, equals a life span of 9 years. Furthermore, she turns two toward the end of 2371, and she would turn 9 toward the end of 2378 (Season 7). They could have had a splendid send-off for her, had she made it to the end.
