FIELD NOTE
"How do you do this thing in Minecraft" turned into a creepypasta.
He searched "how to build a piston door in Minecraft". Thirty-four minutes later he was deep in a creepypasta channel about a Roblox elevator. You want autoplay shut before bed, YouTube Kids reserved for the younger sister, and no history posted to a server.
WHY YOU WANT TO LIMIT IT
Autoplay and the side rail.
The problem isn't any one video. It's autoplay and the side rail. The platform's job is to make sure he never stops, so every next video is a little longer or a little weirder than the one before. For a nine-year-old that's a well-lit corridor with a host that knows his face.
YouTube Kids is the special case. Filtered catalogue, built-in timer, fine as a primary app for a six-year-old. The twelve-year-old already wants "real" YouTube because his friends mention channels Kids doesn't carry, and at some point you'll need to draw the line per-app, not per-account.
WHAT FAMILY LINK DOES
What the usual tools give you (and don't).
Family Link, limited, managed by Google
Family Link supervises YouTube via the "Family Link on YouTube" category. In practice you approve channels (a lot of work) or accept the lax "Explore" filter. Screen time is global, so YouTube and the maths app compete for the same allowance. The behaviour also changes the day your kid turns 13, which arrives faster than you think.
Qustodio, per-app time, all in the cloud
You can give YouTube 45 minutes a day plus a schedule. It works. Each open lands an event on Qustodio's servers, and "we don't read the videos but we know when, where, and how long" is a trail many parents would rather not leave behind a kid.
Bark, watches comments, doesn't limit
Bark alerts you if your child types or receives something concerning in comments. Useful, maybe. Not a "less YouTube on school nights" tool, and a paid subscription where Quiles Familia is free.
THE QUILES WAY
Cap, schedule, separate Kids from regular.
Quiles treats YouTube like any other app. Daily cap, schedule, optional Wi-Fi rule. A sane rule for a ten-year-old:
Example rule
YouTube ✓ 45 min/day · ✗ after 20:30 · ✗ during school hours · ✗ Mon to Fri before 17:00.
One detail that matters: on the younger sister's phone, YouTube Kids can stay open without restriction; on the older one's phone, Kids is hidden entirely and only the main app counts. They're two distinct Android packages and Quiles separates them by default.
When the 45 minutes run out, YouTube doesn't freeze mid-video. Quiles intercepts the next launch, the child sees "Done for today", and if they want more, the "Ask for more" tap lands on your phone with context. You decide in two taps.
THE HONEST GOTCHA
Two packages, two policies.
On Android, YouTube is two separate apps with two distinct packages:
com.google.android.youtube, the main app, no built-in content filter for minors.com.google.android.youtube.kids, YouTube Kids, with a filtered catalogue and its own timer.
This gives you a real choice. You can allow Kids on its own budget (45 minutes) and fully block the main app until the kid is older. When you're ready, flip it: block Kids and give main YouTube a controlled allowance. One tap. Family Link doesn't separate the two at this granularity.
DONE
Cap YouTube without going scorched earth.
