Why We Teach Infant Sign Language — And What the Research Says

What Is Infant Sign Language?

Infant sign language uses simple hand gestures — adapted from American Sign Language (ASL) — to give babies a way to communicate their needs before they can speak. Common signs include 'more,' 'milk,' 'all done,' 'eat,' 'sleep,' and 'please.'

Babies develop the fine motor skills required for signing several months before they develop the vocal coordination needed for speech. That gap — between what a baby understands and what they can express — is often the source of frustration, tears, and the exhausting guessing game that parents of infants know all too well.

Sign language bridges that gap.

What the Research Actually Shows

The benefits of teaching sign language to hearing infants have been studied since the 1980s, and the findings are consistently encouraging:

• Reduced frustration — Babies who can communicate their needs cry less and experience fewer emotional outbursts.

• Stronger parent-child bond — Signing creates meaningful two-way communication between caregivers and infants long before speech develops.

• Earlier vocabulary development — Studies have found that signing babies often develop spoken vocabulary earlier, not later, than non-signing peers. Signing reinforces word associations.

• Cognitive benefits — The act of connecting a gesture with a meaning strengthens the neural pathways that support language, memory, and abstract thinking.

• No speech delays — A common concern among parents is that sign language will cause their child to rely on gestures instead of speaking. Research does not support this. Signing children speak on the same developmental schedule or earlier.

The American Academy of Pediatrics has noted that baby sign language can be a useful communication tool, particularly for supporting children who are slow to develop verbal language.

How We Teach It in Our Little Dreamers Classrooms

Our Little Dreamers program serves children from six weeks to twelve months. Once infants reach approximately six months — when developmental readiness begins — our caregivers begin introducing signs consistently throughout the day.

Signs are introduced during natural routines: mealtime ('eat,' 'more,' 'all done'), diaper changes, nap transitions ('sleep'), and play ('please,' 'help'). Caregivers model each sign while speaking the corresponding word aloud, reinforcing the connection between the gesture and its meaning.

We track each child's progress and share milestones with parents through our communication app so that families can reinforce the same signs at home. Consistency between the classroom and home environment accelerates learning significantly.

What This Means for Your Child's Future Learning

The benefits of infant sign language don't stop when a child begins speaking. The practice of making intentional associations — between a movement, a word, and a meaning — lays a neurological foundation that supports:

• Early literacy and phonological awareness

• Math reasoning and pattern recognition

• Emotional self-regulation (children who can communicate frustration are less likely to act it out)

• Social confidence and empathy

By the time a Little Dreamer transitions into our Explorers program at twelve months, they already have a working vocabulary of gestures — and often several spoken words to match. They enter their toddler years with a head start that most of their peers simply don't have.

A Note to Skeptical Parents

We understand that infant sign language sounds, at first, like an optional extra — a nice-to-have that belongs in a parenting book rather than a daycare curriculum. We thought the same thing before we saw it work.

What changed our minds was watching babies who couldn't yet say a single word communicate complex ideas: 'I want more of that.' 'I'm tired.' 'I need help.' And watching their parents — during pickup — light up when their seven-month-old signed 'milk' for the first time.

That moment of mutual understanding, weeks or months earlier than most families experience it, is something we get to help create. It's one of the reasons our educators love what they do.
