Meet Lumi

Lumi is a warm, playful character who helps babies and toddlers discover the world of words, signs, and communication. Lumi knows that every child has something to say — even before they have the words to say it.

Lumi's world is built around the science of early language: that babies understand more than they can express, that communication starts before speech, and that parents are the most powerful language teachers in the world.

Lumi's World

Through books, sign language guides, flash cards, plush toys, and activities, Lumi helps families create rich language environments at home. Every Lumi product is grounded in research on how toddlers actually learn words — not just hearing them, but seeing them, touching them, and experiencing them in context.

For Families

Lumi is for families who want to give their children the best possible start with language. For parents who talk to their babies even when it feels like no one is listening. Because they are always listening.
