Today, foreign languages are becoming more and more important. This also applies to professional life. As a result, the number of people learning foreign languages has increased. Many parents would also like their children to learn languages. It is best at a young age. There are already many international grade schools worldwide. Kindergartens with multilingual education are becoming more and more popular. Starting to learn so early has many advantages. This is due to the development of our brain. Our brain builds structures for languages up to the age of 4. These neuronal networks help us in learning. Later in life, new structures do not form as well. Older children and adults have more difficulty learning languages. Therefore, we should promote the early development of our brain. In brief: the younger, the better. There are also people, however, who criticize early learning. They fear that multilingualism overwhelms small children. Besides that, there is the fear that they won't learn any language properly. These doubts are unfounded from a scientific standpoint though. Most linguists and neuropsychologists are optimistic. Their studies of the topic show positive results. Children usually have fun in language courses. And: If children learn languages, they also think about languages. Therefore, by learning foreign languages they get to know their native language. They profit from this knowledge of languages their entire life. Maybe it's actually better to start with more difficult languages. Because the brain of a child learns quickly and intuitively. It doesn't care if it stores hello, ciao or néih hóu!
