I'm with CailinDana on everything.
It is different once you have kids. Sorry but it is. It's just a fact of life, and we can tiptoe around it, but you view things differently.
Now, I'm sure lots of people shall be along to say otherwise, but on a general level, a lot of things change. As a woman, for example, you wake up to feminism in a new way - the economics of childcare, the breastfeeding debate etc., etc. that simply aren't as pressing when they aren't directly affecting your every day living standard, career prospects and such. You can empathise, you can imagine - but, you can never directly experience it. And the two are very, very different.
And I think what Cailin is also alluding to is exactly the problem I have with the likes of Owen, well meaning though he may be. His agenda is one formed in a theoretical test tube - he hasn't lived half - or any - of the things he's so desperate to ameliorate.
