Well yes. it gets nuanced. The answer is anyone involved in raising the child. Both parents, grandparents that are still working even. Neighbors, aunts, uncles

Well yes. it gets nuanced. The answer is anyone involved in raising the child. Both parents, grandparents that are still working even. Neighbors, aunts, uncles.. We are both WFH/hybrid which allowed us the flexibility to work crazy work hours and swap hands to take care of children. My wife works 50-65+ hours 6mo of the year and 40 the rest so having that flexibility between 3pm and 8pm really helps. If you have to RTO that flexibility disappears and just crushes work life balance because it's not acceptable to just leave the office at 2:30. If everyone you know if stuck at the office or in a commute till 6pm there is no shared community to help with the child.
