> Even if we think that we should describe mothers as birthing persons
Mother definitely does not mean birthing person. The easiest example is adoption.
Would would you call the mother in that case? Adoptive Female Parent goes again against the 'rule' because it has female in there. Parent 1/Parent 2? no it has Hierarchy.
A female parent is a mother. That's what their children call them, not "parent", with allowances for foster children and older adopted kids calling them by their first name.
I don't think calling a parent 'mother' is something children do by themselves. They call them however they end up calling them, or whatever their parents teach them. Also certainly not 'mother', rather 'mum', 'mom'... and the Turkish children say anne.
