"You're not painting a very good picture of sahms really"
Yes that's because the only picture you see is the one you want to see.
But it's not true. Come to where I am and I'll show you it's not true.
If a family can afford to have one person working part-time or SAH, then they may well do that. It's not rocket science.
If a woman has the choice to SAH, she may well take it. Again, not rocket science. She looks at the financial circumstances of her family. For some women, SAH will be something if a risk, but nevertheless, it's a risk they're prepared to take. Simple as that. But equally, for other women, it's not a risk at all and this is how and why they do it.
If I thought being a SAHM round have rendered me, or more importantly my children, at financial risk, I would never have done it! It really is as simple as that. As it is, I am less financially vulnerable for having been a SAHM than if I'd been working these last 20 years or so. And so are my children.
