The language children need to use socially is much less complicated (for example, playing tag versus talking about world events). And because children are used to making mistakes at everything, from falling off a bike, to not knowing the words for things, and because many of them are naturally quite talkative, they are usually less anxious about making mistakes in the second language. So, the nature of children’s environments mean they are able to dive into second language learning, trying out the new forms right away and often making rapid progress.
