The families where the parents can work from home are not the concern. The families that are of concern are the ones where parents can not work from home: in service jobs and hospitality, for instance. These are the people with the most to lose (bad job security and low pay) and have the least flexibility in their work schedules already. And this is going to inordinately affect them compared to other groups. As far as I’m aware this is still one of the largest (if not the largest) employment sectors in the economy, so it applies to a lot of families.
Even if you are working from home, a toddler is going to require continuous supervision from at least one adult. But thankfully Washington state hasn’t closed the daycares down (yet).
