The [father], [fatherhood] or [dad] of all tag synonyms?

Question

In case parents is not specific enough, there are currently the following tags:

1) Female

mother

2) Male

dad

fatherhood

---

Only fatherhood currently has a tag info:

Questions about being a father specifically, as opposed to a parent, where the gender of the parent is specifically relevant.

This makes clear that fatherhood is simply a synonym of dad.

---

What to do about the situation regarding dad and fatherhood:

1. Declare them tag synonyms?
2. Could fatherhood have a potentially different meaning and so change the tag info instead?

Answer 1

I believe that we need only those three tags:

parents

mother

father

This means that father would have to be created and both, dad and fatherhood, to become its tag synonyms.

This would keep it more consistent (mother & father) and less colloquial (even though dad is probably widely understood, everyone who learns English surely knows father).

I'm not sure if fatherhood could have a meaning of its own - judging from the questions this doesn't seem to be the case.
