It's a good question freya. I'm not sure how to answer it necessarily, because I do have equal parenting with my DH and have done since day one. But I know we are quite lucky in this regard.
I do think part of it is down to the individual, in that women need to avoid fuckwit partners and be assertive about sharing the load.
But a lot of it is down to society though, and I do hope things are changing. I think the new paternity leave is a huge step in the right direction -- I think women are so disadvantaged early on because they are the only ones who can take so much paid time off.
We need more high-level men to take time off so that it becomes okay for lower-level employees to do so. etc and so on. I think we will get there slowly.
I think in the meantime, as I said earlier, we should really embrace 21st century technology and rethink our usual styles of work and education. Do people really need to be in the office and the classroom all the time, at the same time? How can technology make things more family-friendly?
I don't think the issue is one specific student and her hopefully perfect non-crying, non-puking baby. If we really want mothers to still be in school and the workforce, we need more creative solutions than just letting them bring their babies everywhere. That's not going to work for everyone.
