That’s exactly right. My kids’ VLAN goes down at 8pm every night, and they are aware of it. So much so that they usually just shut down at around 7:30pm and start asking for dinner.
Evidently, I audit their network usage regularly and if I find anything concerning, I sit down with them and my wife and talk about it (have found 1 instance in which my boy was looking for pirated games for Linux, and my daughter was looking for “pranks for school and how not to get caught” 🤣).
All in all, I think we nerds have an easier shot at parenting than most people.
