It seems that one way forward might be to extend paid parental leave for both parents. It depends on access to childcare, but I feel it’s hard to be back to 100% at work within the first 2 years of a child being born in any case.
This might help level the playing field. It might also help fathers take a more active role in raising children (unfortunately fathers still appear to be generally less active in this area):
