Title question. Asking so I know before I go and change tags on a bunch of posts, because it might break a lot of stuff if I'm wrong.
I tend to see a lot of posts slip through my blacklist of characters giving birth to live young - I leave birth unblacklisted so I can remove the tag from oviposition related posts [and other unrelated posts] as they show up. However, a lot of people don't seem to tag young, which I do have blacklisted, or baby or even newborn (which honestly should be implicated/aliased to baby or young) on posts of characters actually giving birth.
It does seem obvious that one should tag young when in regards to live birth - but a lot of them slip through, and I'm not exactly sure where the line is. birth -young has several pages of posts.
Is the line drawn at crowning? Or would one only tag young if the offspring is fully born in the image? How about monster offspring such as grubs, worms, and slimes? Monster offspring in particular seems to be in a hazy area in regards to what people tag - I suppose they're usually depicted as "ageless" and not actually babies, but they're still being born.
The wikis don't seem to go into detail on how birth-related age tags should be applied, so answers would be appreciated.
