I have a kindergartener and left my job at the end of March to volunteer on COVID efforts. Now, a month and a half into it, I work from ~6a-12p ET, then take over homeschooling while my wife works from 1-6p. When working, we're in the attic and not to be disturbed, and we keep pretty strict about that.
I've always said that working parents know how to make the most of their 8-hour days in the office, and that's only been amplified. In general, I'm pedal-to-the-metal for my 5-6 hours a day, and then have our family lunch hour to recover before the not-really-relaxing homeschooling begins. We'll get a spot of work in most evenings, half-an-hour of TV, and then it's to bed to start it again the next day.
As for my wife and I, we're both mostly exhausted and guilty – guilty that we're not getting more done at work (even though I'm volunteering!), not doing a better job on homeschooling, etc.
When it's time to get a new job on my end, I'm really nervous about how it's going to go. I'd typically be doing 10-plus-hour days as I ramp up on new teams and material, but that's just impossible these days. In a normal world, I had lots of arguments for why a business should want to hire working parents, but right now it's really tough to justify.
My kid is great, and certainly not a "tough" child by any real measure, but still... Camps and schools can't open up soon enough.
