I agree 100% with arses. No choice is ever easy or straightforward or without complications once you have a child. Or at least that's my experience and the experience of those around me. It's about achieving a balance but then again the balance is never quite right. With the exception of families who are super wealthy & think nothing of having a full time live-in nanny & to leave the childcare completely to her (and I've seen families with this set-up with SAH mums) the rest of us just muddle along as best we can.
I belong in the part-time working mum camp (at the moment unemployed actually so more SAH), and to be honest I sometimes find my days at home with DS- age 2- mind-numbingly boring. On those days the time just doesn't pass. There are other days with DS that are great fun. In general I enjoy & value my time with him & feel lucky that I work part-time and not full-time, and I hope to continue this way. The bottom line is that I always love having DS around, and I know that sounds like a paradox when I've just said all those negative things about having some boring, unbearable days. But that's the normal ambivalence of having and being with children, I think.
I am always extremely surprised that there are women who find everything about staying at home so delightful, when it can be unrelenting, boring and at times extremely irritating and unrewarding work. Spending time with children can also be a lot of positive things, but I think we know those as I assume we all love & care for our children (regardless of our working choices). It's the negative stuff that's not talked about so openly.
I think that both WOH and SAH are choices that have pros & cons but on balance I would always give my vote to mothers who work, as I feel that's offering themselves & their children a more balanced, long-term, realistic, open-minded view of life. That's my belief but I know each case is very very different. For a woman who is used to be immersed in a job she loves, who is also used to making her own money, it can be very hard or even impossible to stay at home full time and it may be, for many women, that it's simply not the right choice at all.
So all these debates feel beside the point when in reality there's no way (in most cases) that a woman who has spent years working in a field she loves & values would give that up completely to look after her children full-time when she can often access good childcare & use the help of her DP too. Assuming that giving up work & staying at home would be the right choice for these kinds of women and their children is so wrong-headed, when clearly, clearly it's not the right choice in so many cases: more and more women are going to work after having children, that's the reality despite any 'trend' towards staying at home motherhood which I believe is unimportant in the large scheme of things. This is what makes these debates so infuriating & insulting. It's not selfish & not a thing to be ashamed of if someone loves their work & values it and wants to do their work. And very often SAHMs try to guilt-trip working mums, and I feel that's what's shameful, actually. If someone enjoys doing childcare all day, that's fantastic, go for it. But don't make others feel bad to justify your own choices. If someone doesn't want to do childcare full time, fine too.
