The goal for this age. Keep it simple. One shared device. One profile. Co-use, don’t hand it over.

What you’re protecting against

  • Autoplay rabbit holes (YouTube, TikTok) that surface inappropriate content.
  • Accidental in-app purchases.
  • Inappropriate recommendations and ads.
  • Strangers in voice chat on multiplayer games.

Your 30-minute setup

  1. Use a shared device (family iPad, Fire tablet) — not a personal profile for a four-year-old.
  2. Install YouTube Kids, not YouTube. Set the age filter. Turn off search if you want maximum control.
  3. Turn on Screen Time / Amazon Kids+ / Family Link depending on your device.
  4. Require password for all purchases. No exceptions.
  5. Download apps in advance so your kid can’t install new ones.
  6. Put the WiFi router on a family DNS (NextDNS, Cloudflare Families) — see our router guide.
  7. Set a bedtime routine: device goes in the kitchen at 7pm.

Recommended setups by device

  • iPad: Guided Access for single-app mode, Screen Time for overall limits. iPad guide.
  • Amazon Fire: Fire Kids Edition + Amazon Kids+ is the easiest turnkey option. Fire guide.
  • Android tablet: Google Kids Space profile. Android guide.

What to skip at this age

  • Personal smartphones. There is no good reason.
  • Messaging apps. WhatsApp, iMessage, Snap — none of these.
  • Online multiplayer games with voice chat. Wait.
  • Social media. Below the legal COPPA minimum anyway.

Conversation starters

  • “If you see something scary or weird, you come get me right away. You’re never in trouble for that.”
  • “We watch YouTube together, not alone.”
  • “No typing to strangers. Not ever.”
