Baby Keyboard Lock
Hand the keyboard to your baby — every key just makes fun colours and sounds, full-screen, with nothing else it can do.
Ready for Baby Mode?
Fills the screen with colours and cheerful sounds on every key press or tap — no meaning, just fun.
Whichever mode you pick, typing, scrolling, the back button, and closing the tab are all switched off — hold the small button in the corner, or type “parent” on a keyboard, to get out.

Tip: turn your device volume up so the sounds come through.
On iPhone: Safari can’t hide its own address bar, so tapping it can still leave the page. For true full-screen with nothing else tappable, tap Share → Add to Home Screen once, then always open Baby Mode from that Home Screen icon.
Turn any keyboard into a safe toy: start Baby Mode, hand it over, and every key press or screen tap fills the display with a burst of colour, a big bouncing letter, and a cheerful chime — instead of typing into whatever you were working on, closing a tab, or opening a browser menu.
There are five modes to pick from before you start. Play Mode is pure sensory fun — big colourful bubbles and confetti sparkles burst out from wherever a key is pressed or the screen is tapped, with a different playful sound (a chime, a sparkle run, a cartoon boing, or a soft pop) picked at random each time. Learn Mode shows one big flashcard per press — the letter or number, a matching word and picture, and it's spoken aloud. Word Mode shows the same flashcard but speaks the word instead — press A and hear "Apple". Read Mode needs no input at all: it works through every letter and number on its own, speaking each one and its word in turn. And Quiz Mode asks "Where is A?" with a few options to tap — a right answer is celebrated out loud, a wrong one just says to try again.
It's built to hold up against more than just typing — a flat little hand hits the mouse, trackpad and mouse buttons just as often as the keys. So alongside typing and scrolling, Baby Mode also blocks the scroll wheel, the mouse's back/forward buttons, and the browser's own Back button, and it throws up the browser's native "leave this page?" confirmation if anything tries to close the tab or reload — a barrier a baby's random taps can't click through. There's no keyboard shortcut to get out either: the only way to leave is to press and hold the small exit button in the corner, which random taps won't land on by accident.
One thing to know: a handful of things are decided by the operating system or browser, not the website — switching apps (Alt+Tab / Cmd+Tab), the physical power button, and exiting full-screen with Esc can't be intercepted by any page, no matter which one. If Esc knocks it out of full-screen, Baby Mode itself stays fully on — just tap the button that appears to go back to full-screen.
Which mode suits which age
| Mode | Roughly | What the child gets from it |
|---|---|---|
| Play | 6 months – 2 years | Cause and effect: I did something, something happened |
| Learn | 2 – 4 years | Letter recognition with a spoken name and a picture |
| Word | 3 – 5 years | Letter-to-sound association — A says 'apple' |
| Read | Any age | Passive exposure; useful when a child won't press keys |
| Quiz | 4 – 6 years | Active recall rather than recognition |
Ages are a rough guide. What matters more is whether the child is still exploring cause and effect or has started attaching meaning to the symbols.
What a website can and cannot block
It's worth being precise about this, because a tool like this is only as useful as its honest limits. A web page runs inside a browser, inside an operating system, and each layer above it reserves certain inputs that no page is permitted to intercept — deliberately, as a security measure.
- Blocked here: all typing, scrolling, the scroll wheel, mouse back/forward buttons, the browser Back button, and context menus.
- Guarded here: closing the tab or reloading triggers the browser's own confirmation dialog, which needs a deliberate click to dismiss.
- Not blockable by any website: Alt+Tab and Cmd+Tab app switching, the Windows key, the physical power button, and Esc leaving full-screen.
- On iPhone specifically: Safari has no full-screen mode for web pages, so its address bar always remains on screen. Adding the page to the Home Screen and launching it from there removes Safari's interface entirely.
- The practical implication: this reliably protects your work and your browser tabs. It is not a substitute for supervision, and no web page could be.
Screen time, briefly and honestly
Major paediatric guidance — including the WHO and the American Academy of Pediatrics — recommends no screen time for children under 18 months apart from video calling, and limited, co-viewed screen time up to age five. A tool like this doesn't change that advice, and it would be dishonest to present it as educational cover for handing a toddler a laptop.
Where it genuinely helps is the specific situation it was built for: a child is already at the keyboard, and the realistic alternatives are a deleted document, a closed tab, or a browser in a state you can't recover. In that moment, ten safe minutes is better than the alternative. Co-use it where you can — a child pressing keys while an adult names the letters gets far more from it than the same child alone.
Frequently asked questions
- What's the difference between the five modes?
- Play Mode is pure sensory feedback with no meaning attached. Learn Mode shows a flashcard per press and speaks the letter or number. Word Mode shows the same card but speaks the matching word instead. Read Mode plays through the whole alphabet and numbers on its own, without needing any input. Quiz Mode asks where a letter or number is and checks the answer you tap.
- Can I use Learn or Word Mode on a phone or tablet with no keyboard?
- Yes — those two modes show every letter and number as its own button on screen, so tapping one works exactly like pressing it on a physical keyboard. Tapping anywhere else on the screen still shows a random one, same as a real key press would.
- How do I exit Baby Mode?
- Press and hold the small circular button in the corner of the screen until the ring around it fills — about a second and a half. A quick tap won't do it, so a baby's random presses can't exit by accident.
- Can my baby accidentally close the tab, hit back, or open another site?
- Baby Mode blocks typing, scrolling, the scroll wheel, the mouse's back/forward buttons, and the browser's Back button, and it triggers the browser's own confirmation dialog if anything tries to close the tab or reload the page — which needs a deliberate click to get past, not just a mash. App-switching shortcuts like Alt+Tab and the device's own power or home button are decided by the operating system, not any website, so no page can block those.
- Does the speech need sound or an internet connection?
- Learn, Word, Read and Quiz modes use your browser's own built-in voice, and the chimes are generated locally too — no audio files to download and nothing is sent anywhere. If your browser has no voice installed, those modes fall back to showing the card without speaking it.
- Why does it ask for full-screen?
- Full-screen hides the browser's address bar, tabs, and bookmarks so a curious tap can't land on any of them. If your browser blocks full-screen, Baby Mode still runs and still blocks typing and navigation — it just won't hide the browser chrome.
- On my iPhone, tapping the screen sometimes still leaves the page — why?
- iPhone Safari has no full-screen mode for web pages at all, so its own address bar stays on screen no matter what a website does, and a tap can land on it. The fix is to install it like an app: tap Share, then Add to Home Screen, and always open Baby Mode from that Home Screen icon afterwards — it then opens with none of Safari's own bar or buttons on screen.
- Is it safe to leave a child alone with this?
- It protects your work and your browser, not your child. Treat it as a guard against accidental damage rather than a reason to step away — and note that paediatric guidance recommends screens be co-viewed at these ages anyway.
