It's worth noting that women can certainly nurse while working if we want to. Lots of us have done it. I did it. So did my daughter. I've known hundreds of moms who did. There are even new pumps that are wearable (under your shirt) so that you can discreetly keep pumping even if you work a job that makes it difficult to take pump breaks. Mothers do not need to choose formula just because they're working. A decent maternity leave would, of course, make it MUCH easier and it's horrible that we don't offer that to every parent.
