Like the rest of us, children are individuals. What makes them different from adults, as a whole, is that children are reared in adult worlds according to adult expectations. Children learn to model their behaviour on what goes on around them, be it dress codes, body language, table manners or language uses, usually first through their caregivers and later through peers in their family, neighbourhood or school. That is, children are learning how to function adequately in their environment, and much of this learning takes place through language itself. We talk to children to tell them about our adult world and they learn about the world from what we tell them. But they also learn about our language, from how we use it to tell them about other things. This means that language learning is going on whenever language is used around children.
