Here's a question (not to derail the thread further )-Spock talks about planned colonies and societies in "Way to Eden":
The idea of planning out communities may include birth and reproduction planning as well. So, given the increase security/response to the Narada's attack, the Chekovs had to postpone having their child, in similar circumstances to Nerys Myk's scenario.
Spock said:"There are many who are uncomfortable with what we have created. It is almost a biological rebellion -- a profound revulsion against the planned communities, the programming, the sterilized, artfully balanced atmospheres. They hunger for an Eden--where spring comes."
