To wish that there would sometimes be some recognition that there is a middle ground between mothers parents who work 50 hours a week, and those who SAH.
WOHM could include anyone on a spectrum from working a couple of hours a week in the local shop, to working 50-60 hours a week in the City.
AIBU to think that the term WOHM, in the context of the kind of debates we have on MN, and in the media, is therefore a bit of a silly 'capture all' term.
