Husband is WFH as a programmer. It's not an ideal setup: he has to VPN over to his workstation in his office a lot. He relies on noise-cancelling headphones and a really good chair, two splurges, to stay sane while working in a small house with two kids. (Sibley, spend the money and get a nice chair.)
We're doing the best we can with a 7-year old and a 9-year old. I don't know about other people, but I'm glad I'm not working (SAHM), because I'm now a full-time child psychologist, teacher, and entertainer.
The kids have lost their social circles, routine of school, and everything they liked to do outside the house. The parks are all closed. They're clingy and emotional and rambunctious when they're not obnoxious, which means I have to manage them and manage to keep them from bugging my husband who is trying to work. They have gotten SO demanding, constantly jumping on me and trying to get my attention. I can send them outside but there's only so much to do outside our house. And of course there's a scary invisible virus out there, which is freaking them out no matter how reassuring I try to be, because they're worried about their grandparents. The kids are getting lots of headaches, lots of bad sleep, and lots of nightmares, which makes them even worse during the day.
I am *this close* to buying a trampoline and putting it on our front yard just to give them something active to do, because they can only bicycle around the block so many times.
