One lesson we learned is that one of our kids has attention-deficit problems. They were not a concern at all in the schools because the classroom was managed in a way that worked for him. But at home during the pandemic, it was a disaster. It took us most of the year to figure out what was wrong, get plans in place, work with the remote teachers, and get even a semblance of a good education going.
I'm not against homeschooling - I love it in theory. But people need to be prepared to adapt to the childrens' needs. What works for one person will not work for others, and you should know what you are getting into.
