How to Lock Your iPhone Screen for a Baby (So Taps Do Nothing)

Quick answer: Open the video or app first and get it playing. Then triple-click the side button (the Home button on older iPhones) to start Guided Access, tap Options, switch Touch off, and tap Start. The screen now ignores every tap and palm press. Switch off the side and volume buttons in the same Options menu. To finish, triple-click and enter your Guided Access passcode. On iOS 18 and earlier you double-click to end instead. Turn Guided Access on once first in Settings > Accessibility > Guided Access.

A baby doesn't try to escape your phone. They grab it, slap it, and press their whole hand on the glass, so the video pauses, a FaceTime call starts, or the screen ends up in your photo library. What you want here is not a parental control. You want a screen that ignores touch until you say otherwise.

The iPhone can do this with a built-in feature called Guided Access. No app is needed for the lock itself. This guide covers only that job: freezing the screen for a baby. If your child is older and deliberately swiping out of apps, read how to stop a toddler exiting apps on iPhone instead.

Before the first time: turn Guided Access on

You only do this once.

1. Open Settings > Accessibility > Guided Access and turn it on.
2. Tap Passcode Settings and set a Guided Access passcode. You can also allow Face ID or Touch ID to end a session.
3. Check Display Auto-Lock on the same screen. It controls how long the screen stays on during a session, separately from your normal Auto-Lock. If the screen keeps going dark mid-video, this is the setting to change.

Apple's Guided Access instructions describe every setting if your screen looks different.

Lock the screen: the order matters

The usual mistake is switching Touch off before the video is playing. Then nobody can press play, including you.

1. Start the content first. Open the video and press play, or open the activity your baby will look at.
2. Triple-click the side button. On an iPhone with a Home button, triple-click Home. The Guided Access setup screen appears over the video.
3. Tap Options. Turn Touch off. Check the buttons as well:
   • Side Button (Top or Home on some models) off, so a grabbed phone doesn't lock or wake.
   • Volume Buttons off, so the volume stays where you set it.
   • Motion off if you don't want the screen to rotate when the phone is tipped.
4. Set a Time Limit (optional). Pick a short session length, for example ten minutes.
5. Tap Start. The video keeps playing and the glass is now inert.

Test it before you hand the phone over: press the screen with your palm and push the buttons. Nothing should happen.

Want some taps to work?

Leave Touch on and, on the setup screen, draw a circle with your finger around the parts of the screen that should ignore touch, such as the player controls, a "next video" panel or an ad banner. Apple describes this as making "parts of the screen stop responding to touch". Taps everywhere else still work. This suits an activity your baby taps, not a video they watch.

Getting back out

Triple-click the side or Home button, enter the Guided Access passcode (or use Face ID or Touch ID if you allowed it), then tap End.

On iOS 18 and earlier you double-click instead. Apple changed this for iOS 26, so if you have used Guided Access before and it no longer responds, that's probably why.

If you set a Time Limit, the screen shows a message when it runs out. The phone stays locked in the app until an adult triple-clicks and enters the passcode. Your baby can't get out, and neither can anyone who doesn't know the passcode.

One safety point

Apple states that Crash Detection and Emergency Services aren't available while Guided Access is on. That's a reason to keep sessions short and supervised. If you need the phone for an emergency, end the session first.

Lock screen, Auto-Lock and Guided Access are different things

Searches for "lock the screen" mix up three different features:

Feature	What it does	Does it stop a baby's taps?
Lock screen (side button press)	Turns the display off and locks the phone	Yes, but the video stops showing
Auto-Lock (Settings > Display & Brightness)	Turns the display off after a period of no touch	No
Guided Access with Touch off	Keeps the app on screen and ignores touch	Yes

Only Guided Access lets the baby see the screen while their hands do nothing.

Where Baby Screen Lock fits

Guided Access with Touch off is the right tool for a video. It isn't much use when you want your baby to tap, because every tap now does nothing.

That's what our app, Baby Screen Lock, is for. It fills the screen with simple tap-to-play activities: bubbles, animals, high-contrast shapes, a xylophone. Each tap gives a sound and a gentle haptic. A parent lock hides the exit controls inside the app. To leave, an adult taps the lock badge three times quickly, then answers a maths question. You can also set a session timer (5 to 30 minutes, or unlimited).

To be clear about what an app can't do: no iPhone app can block the Home gesture, the side button or notifications on its own. Only Guided Access does that. Baby Screen Lock includes a step-by-step Guided Access guide, and we recommend using both: start an activity in the app, then triple-click to start Guided Access with Touch left on.

Baby Screen Lock is free to download. Full access needs a subscription or a one-time lifetime purchase. It is also on Android, where the app can ask the system to pin the screen during a session.

FAQ

How do I lock my iPhone screen so my baby can't touch it?

Start the video, triple-click the side button (or Home button) to open Guided Access, tap Options, turn Touch off, then tap Start. Turn Guided Access on first in Settings > Accessibility > Guided Access.

Why can't I press play after turning Touch off?

Touch off disables the whole screen, including the play button. End the session, start the video first, then start Guided Access again.

How do I unlock Guided Access?

Triple-click the side or Home button, then enter your Guided Access passcode or use Face ID or Touch ID, and tap End. On iOS 18 and earlier, double-click instead.

Can I stop the volume buttons working while my baby holds the phone?

Yes. In Guided Access Options, turn off Volume Buttons before you tap Start.

Is it safe for a baby to watch videos on a phone?

That's a separate question from locking the screen. We cover it, with current American Academy of Pediatrics guidance, in Baby watching videos on your phone? A safer iPhone setup.
