If you are looking for a parenting approach, legal seems unnecessary. If not, is the question really on topic? Especially considering that there is Law.SE? A tag like legal is only necessary for questions about legality of something, but should this be our focus? Note that there are already tags that touch upon law or legal issues, like custody or adoption and they may already be sufficient.
The only question I found where it seems appropriate is a list-type of question that's a bad fit for the SE model anyway. And a broader tag, that's applicable to more questions, may be better for such cases.
Comfort
There are currently 6 questions tagged comfort.
No tag wiki excerpt.
It looks a bit like a meta tag to me and I'm not sure what it's trying to say. If it's about how to comfort someone, it should rather be comforting. But it seems easier and more convenient to tag it with the goal instead, e. g. the often used emotional-well-being.
The only question where comfort seems appropriate could do very well without it and emotional-well-being instead.
Running
There are currently 3 questions tagged running.
No tag wiki excerpt.
For sports, we already have tag sports and if it's about children learning how to walk, there's walking. Instead, running seems overly specific and was therefore seldomly used. The older two questions actually can do without that tag and I would add sports instead, while the newest one may need neither walking nor running, but discipline instead.
What do you think about these tags? Are they needed or not?
