I didn't really have the option, as DD's Dad was studying when we became pregnant with DD, and we agreed that after my maternity leave I would return to work and he would return to uni and be a SAHD. I was looking forward to him finishing uni and getting a job so that I could cut down my days at work, but we broke up before that happened, so being a single mum I couldn't cut down.
I am a lawyer and until this year worked at a private law firm. In some respects it was flexible and family friendly, but in terms of career progression I was basically stalled due to not being able to do the same sorts of hours and make the same sorts of commitments as my childless colleagues. Or those who had children but also had a partner who did most of the child care/home duties.
This year I took up a contract as a senior lawyer in the public service and I love it! My job is no longer primarily about billing and profits and making the partners richer, and more about just straight up doing my job well.
