What baby sign language is
Most babies understand far more than they can say. Between roughly 6 and 18 months there is a gap: they know what they want, but the words are not there yet. Simple hand signs bridge that gap. The signs used with babies come from American Sign Language (ASL), kept simple enough for busy parents, grandparents, and caregivers to learn.
When your child outgrows baby signs, the natural next step is the full alphabet: our free ASL fingerspelling tutor teaches all 26 letters with live camera feedback on your hand shape.
Parents usually start with a handful of high-value signs: milk, more, eat, all done. Add new ones as your baby masters the old ones. Consistency matters more than quantity: use the sign every single time you say the word, and celebrate every attempt your baby makes.
Why parents use it
The big win is fewer meltdowns. A baby who can sign milk instead of screaming for it is a calmer baby, and a parent who understands the request is a calmer parent. Signing also gives you a window into what your baby is thinking about, from the dog across the street to the book they want read again.
The common worry is whether signing delays speech. Research has not found that effect: signing is a bridge to speech, not a replacement for it. Always say the word out loud while you sign, and keep talking to your baby as much as you otherwise would.

How Little Hands works
- Open the app at toollantern.win/little-hands on your phone. Nothing to install.
- Pick a sign and watch the reference so you know the target shape.
- Hold up your hand to the camera. The app checks your hand shape, the adult learner's signing, live and gives specific hints, such as spreading your fingers or moving your thumb to your chin, until the sign looks right.
- Quiz mode tests whether you remember the signs without the reference.
- Your progress is saved on your device only. The camera turns fully off when you leave a lesson.
Your video never leaves your phone
Everything in Little Hands runs on your device. Your camera feed is analyzed locally by a hand-tracking model that ships with the app, and a strict security policy blocks the page from contacting any outside server. There is no account, no analytics, and no recording. After your first visit the app saves itself to your phone and works fully offline.
