I was an accountant previous to having my DS's (3 years and 10 months). We also plan another one or two, so no chance I'm going back anytime soon.
I love it, and we are happy for me never to return back to work, but the option is there if I needed to.
I spend my days looking after my family, cooking, cleaning etc, as well as finding some time for myself. This obviously suits some women more then others, each to their own.
I wouldn't change it for the world. My mother was a SAHM and now her children have fledge the nest, she's a housewife, and my parents are quite content with their own little bubble. Again, some people wouldn't like it, but they thrive in it.
Some people wish they were SAHM because they resent having to return to work.
Some SAHM only wish they could return to work, but can't due to say care issues or childcare costs.
Some working mum's love it, earning the extra money. Some SAHM love it, providing at home. Either way, whatever mum you are,there is sacrifices made, so give each other a break, being a mother is hard enough already..
I don't really think anyone has a say on how someone else lives their lives. What works for one family, may not work for another.
