I think we need to create a few synonyms for the children:
- kids
- infrant(s)
- toddlers
Synonym mapping for 'infant' already existed, I added the others. Tags don't need to be created before one is legitimately used (unused tags get cleaned up anyway) but I feel synonyms are essential to help new users tag posts correctly. (For instance, someone posting about children could think the word 'kids' and not have a suggestion pop-up because it hasn't been set as a synonym.
I don't think we need to create synonyms until they have been actually used by someone. Pre-emptively increasing the number of tags doesn't sound like good idea to me -- we have a ridiculous amount of tags already, and there's no need to increase it unnecessary.
