That kind of defeats the purpose of "shelter in place", doesn't it? With so many asymptomatic carriers and children being germ magnets, those babysitters are going to become a very effective vector for spreading the virus.
Then you either have people whose situation worsens due to coronavirus illness or people whose situation worsens since they can't earn money and instead need to focus on child care. Pick your poison.
I assume that this is exactly why Facebook gives that money to its people. The fewer childcare workers are required to help around while also spreading the virus, the better.
