Patronising? I find it interesting when people take offense to things so easily. How is sharing my personal experience patronising? I didn't say it wasn't hard - or "really, really, bloody hard," but given that there are people mining for coal, risking life and limb in the armed forces, and children digging through trash heaps for a living, I'd venture to say it's not THAT hard.
The first three years of my daughter's life I was also caregiving for a dying parent and working full time. Life is hard. But parents are just as capable - if not more driven and willing to sacrifice - than anyone else and I don't think we should marvel at that (or as in recent news, imply women should freeze their eggs to pursue their careers). People have been having kids and working from the beginning of time. I know women from previous generations who have had ten or more kids and worked full time. Very common in the American South during the 20th century.
