I expect to be able to send the kids to school, perhaps at least a few hours per day. It is impossible now.
An in case the school is not working, I can send them with one of the grandmas or the other. But we are currently in the peak of the pandemic in Buenos Aires and it is a bad idea because they are old so they are in the health risk group. I think it is even illegal here due to the quarantine, but it is a bad idea anyway.
We take turns with my wife to take care of the kids and try to organize the activities, for example to avoid having two Zoom meetings at the same time.
Luckily we can arrange some activities to do them when the kids are sleeping or at least quiet, like preparing / checking / grading midterms at weird hour like 11pm.
One of the problems is that in the middle of a Zoom meeting one of the kids may appear and say hi, or ask to change the tv channel, or perhaps some food, or just hug me for 5 minutes. Luckily in most of my meetings I don't need a 100% of concentration, so a kid going around is not so bad.
