Hundreds of people responding - job done then as far as the writer and publication are concerned! That's journalism for you.
Seriously- if one is content with ones life, then you're not going to rise to such articles. As a WOHP I couldn't give a shiny shit that on some weird mother deification scale I'm supposedly right at the bottom. Why should I?
So long as I am content with my choices, my DH is content and my children are happy and thriving, what does it matter if some people think WOHM is wrong? Likewise, people shouldn't moan about the downsides (and believe me paying out the equivalent of my salary in childcare for years felt like a massive downside at the time) It's hard to work bloody hard in a professional role alongside being a parent of little ones and not be financially any better off at the end of the month, but it's not something id gripe about because I saw it as the long term issue.
I think the article is also making that point: make your choice and get on with it without moaning or trying to make it sound harder than it is. If you choose to stay at home, don't moan about being a martyr or unpaid teacher, taxi driver and all that bolleaux, and if you choose to work, don't moan about having to get up earlier and present yourself as an articulate professional when you've been up changing nappies in the night. Just get on with it!
Of course, the people who really deserve sympathy are those who don't have a choice and are forced into a position they'd rather not be in
