I think the choice of working or staying at home is mostly a function of economics. Before the pandemic usually both partners had to work for a family to have a sufficient living standard. And now if one is forced to stay at home it makes sense for the partner with smaller income to stay at home.
When you talk in terms of fairness you implicitly imply child care is somewhat less desirable than a career and are signaling to women or men who choose such path that they made a wrong choice.
