Single income one with wife as SAHM. We live on one software engineer's salary (not FAANG). We make sacrifices with things like size of our house, etc and feel it's worth it to invest that opportunity cost into our children. I understand that not everyone can live on one income. But more often I see in my circles people that can make it work, but choose not too because they don't want to make that career/financial sacrifice. Instead both parents work and send their kids to daycare. Of course that's totally their choice. I've made a different choice and perhaps this is an unpopular opinion this day and age, but I think it's the best choice if you can make it work financially and are willing to put in the effort that it entails.
