When the school tells my Kindergartener they'll put him in timeout in his own home for getting up to use the bathroom w/o permission.

This is MY house. I decide what happens here. Bathroom breaks aren't a privledge. You got a problem with it, setup a P/T conference.

I'd love to see how that works over Zoom. Like what's the play here? "Go sit in the corner?" They can't assure the child's safety. For all they know the floor isn't safe for a small child. It's a lot of liability with no ability to enforce. It's not school property.

My kids can eat, drink, go to the bathroom and spin around in their chairs if that's what ensures they are present for class and learning. If they need a brain break, they can get up and walk away. I'm OK with ALL of that as long as they're learning and not disrupting others.

The purpose of enforcing classroom rules is to ensure class isn't physically disrupted during a lecture. That disruption doesn't exist in a muted mic zoom class.

What's disruptive is attempting to remotely discipline a 5yr old in their own home over a basic body function.

That's just schools trying to "train" a child for a classroom they'll never visit. Kids are highly contextual and enforcing classroom rules designed for physical classes in a remote learning environment is the worst kind of state intrusion.
