Yeah, it really is. It's a blue state thing. Schooling, public and private, and to some much more limited degree, homeschooling, is intimately linked with your pediatrician. It's not that the school and the doctor talk directly. It's more that you have to bow to the doctor, then get your indulgence records, then shuffle them over to the school administration office and bow there as well. Historically, if you had a spine, you could nail your thesis to the wall and get side eye from the administration, and then carry on not following the rules. But in very blue states like California, they shut that option down a few years back (interesting timing eh?). Now you play ball or presumably the law gets involved at some point, maybe child services.
