It's not clear to me how you can be a full-time employee and be doing full-time child care. I understand the need for schedule flexibility, but if going back to the office means you need to find child care it seems to suggest some of these people weren't really working full time on those days.
And daycare is booooooonkers expensive. I'm sure a lot of people were like "hmm, $3k/mo or constant low-key distraction... how bad can it be"
