I get it. Overscheduling by parents who are largely absent has been a problem for a few decades now. I’m not talking about parents who work two jobs each, or have to put their kids in daycare, but people who think enrolling their kids in a million and one different activities is an acceptable substitute for parenting.
That being said, I don’t think this is that, necessarily. My first thought was that it was for autistic kids who need a regular schedule but might not be able to read yet. Then, I thought that the kid might not necessarily be autistic, but still might need to know when s/he needs to go to daycare, when their older siblings have soccer practice or whatever, when the weekend is, etc. The kid doesn’t need their own schedule to be affected by the schedule of those around them.
