My oldest is starting to get annoyed that he can't go out with his friends, but he has been managing with Xbox and social media. Biggest issue with him is getting his school work done without clean lines of defining time and while I'm trying to stay on top of it, it's not easy in a first world problem sort of way.
Youngest is doing her school work in 30-45 minute intervals with a lot of playtime in between so she is being managed well.
Overall, my wife and I are really doing the teamwork thing well. We are making it a point to talk about the day and if something could have been handled different or better we are talking it through so we are ready the next time. I am going along with her 10 step quarantine procedure when I have to leave the house. I've had days where I took 5 showers because of having to leave the house multiple times just out of poor planning on my part or something happening with work that changed plans.
This really is the time in a marriage where open communication about literally everything is vitally important. When she tells me she needs space or a break or whatever, I drop what I'm doing and make sure she gets it. I have scheduled an hour every day where I sit on my deck with a bottle and a cigar and just relax with music without anyone bothering me and she respects that and makes sure the kids do too.
We are alternating who cooks dinner. Breakfast I do more often than not simply because I wake up first. Lunch is a free for all and we have the pantry and supplies set up for that so the kids don't ask for something, they just get it. If it has to be cooked, though, she does it for them.
We are also making an effort to spend time together when they go to bed. A few nights ago we watched the Les Miserable 10th anniversary concert on YouTube because it's a shared thing we like and just enjoyed each other's company. And yes the bedroom is extremely important as well.
We've certainly both fell victim to assuming something was said or done for a reason that wasn't true. It takes work for sure. But we trust each other, which is also vitally important. All I could offer for advice (as was mentioned above, and if meant seriously) is to really talk about everything. Literally, everything. This is a new dynamic in life and whether any of us admit it or not there is a level of fear, stress and uncertainty that is going to cloud every thought and action. We are meant to be the best of teammates. If you start from that premise it makes everything else easier - not easy, for sure. But easier.
