I love my daughter, and did just as much when she was a youngster, but I think many dedicated spaces are a benefit because they allow for greater focus, because the kids (or spouse or parent or...) are not there. I have seen no data on it, but I have the impression that experienced workers with no dependents do better in a WFH environment, than either new hires or people with family at home.

As a 41 y/o guy without kids I very much agree. I have my bad days when I can't focus well even if I am surrounded by complete silence but I am very grateful for no persistent distractions like kids when I can.

Plus many acquaintances of mine reported that they had to resort to making a small room in their apartment a dedicated home office which they had to lock in order to prevent distractions from their kids.
