Before I had children I used to think that maternity rights for women only were sexist against men. Now I think they're sexist against women.
Until men have the same rights (time off and pay) to women, women will continue to take the main parenting role. The time off (for me 6 months for ds1 and returned full time, 8 months for ds2 and returned 3 days a week) means you play catch up on your return, and when you do get back there is so much to think about organising the kids that career often comes second.
Being a SAHM following the birth of your baby is fantastic but it should be a choice, and it might be that a less career-minded husband could do it just as well.
Equal rights would also stop employers not employing women of child bearing age, or at least make things equal!
What do you think?
