Presumably they employ a full time nanny then, or have lots of family to help raise their children?
We tried having both of us working when we just had one child, that was sustainable for a while. But for DH to climb higher, in a very competitive field, we needed someone always available to care for children and home. We even tried a nanny/housekeeper for a year, but this caused more issues for us. The obvious solutuon for us was for me to become a SAHM, rather than keep using childcare. He needs to be free to focus on work, which involves travelling overseas and working unpredictable hours.
There really isn't much childcare provision, unless you use breakfast clubs, after school clubs, nurseries and can balance it all, to enable both parents to stay employed. How do people manage the school holidays? What if your DC don't thrive in childcare settings and holiday clubs? Obviously it's great if they do, but many children are happier when they have more time with a parent.
I think the value of having a SAHP is under-appreciated by some, maybe under valued in general by entire societies. Very sad that so many SAHMs feel unappreciated or not respected by society.
To me, being able to say I'm a SAHM feels very 'respectable'. I always wanted to take on this role and do it well. Raising and nurturing a family, being able to focus on this exclusively instead of juggling work at the same time, is a privilege to me. We worked and planned for it. I don't care too much if others look down on me for choosing this path. And I don't look down on others for their paths, every family situation is so different nowadays.
