Wow. My wife and I have 3 kids, all went to college.
At the time the first was born, we decided she’d stay home and be a full time mother. She coached them through school and ACT prep, which brought academic scholarships for all 3.
We have friends where the couple both stayed at work. Maybe they take nicer vacations than we do, some sent their kids to more expensive colleges. Oddly, I retired before anyone from that group. Some say they can’t afford to retire.
Trad wife worked out for us. My daughter has a career and is entering marriage age, I’m conflicted about that. I hate for her to leave her career behind, but that’s the path that worked for my wife and me.
