I put in a few tag synonym suggestions I'd love to get feedback on and/or get votes on:
parenting -> parents (Parenting is probably misused for the most part - after all this is Parenting.SE, so all questions should have this - and making it a synonym to Parents might be the easiest solution, as that has usage guidance that should help keep it from being misused)
There's also a longstanding one from Erica out there still that could use a few votes:
I'm going to keep going through tags that don't have wikis, and will probably have some more suggestions. I'll add them to this list, but you can always go to the tag synonym page, also available from Tags -> bottom of the page
tag synonyms link, and then select
suggested, to see what needs votes.
For those that don't know - you need a total answer score of 5 in the tag to vote on the synonym (I don't think you need a particular amount of rep; 1250 is needed on a beta site to suggest the synonym, though). See suggesting tag synonyms for more information!
