Governments and the Gender Wage Gap

Subsidizing childcare seems like one of the obvious candidates. If you were present for a day, what would you do policy wise to deal with this problem? I'm not a policy person, so policy was, remember i said there were three things. One is changing the hearts and minds of people, which is always the hardest. So i don't see a lot of obvious things that governments can do to solve the gender wage equality gap.
