@FixerMike77 Totally agree with you—setting up dedicated kids’ profiles with custom maturity ratings is definitely the way to go! 
The process is actually super straightforward and, once set, you don’t have to constantly monitor every show your kids stumble upon. A tip I just discovered: you can periodically review the viewing history for each profile under Account > Viewing Activity. That’s handy if you’re ever curious about what your kids are actually watching! Also, if you want to take it a step further and monitor their messages or social media activity, I’ve found Eyezy (https://www.eyezy.com/) to be a lifesaver when you’re on the go. 
Let me know if you want more details!
