0-6 years old is a sensitive period for children's language development, but each child's individual differences are very great. Some children's language ability develops rapidly, while others are slow. Usually, it is more important to be under 4 years old. At this time, it is best not to give children too complicated language environment. Parents should grasp a principle, that is, learn their mother tongue well first, and then let their children contact foreign languages after they have a certain oral language expression ability, otherwise it will disrupt their language system, cause confusion of their language concepts, and lead to language development retardation.

A follow-up survey of children who learn English as a second language in Europe found that there was no difference in English level between children who started learning English before the age of 7 and those who started learning English at the age of 7. In other words, 7 years old is the right age for children to learn a second language.

Of course, after the child is 4 years old, the language development is relatively mature. Parents can appropriately create an environment for learning foreign languages and expose their children to English, such as listening to some recordings, nursery rhymes and watching original cartoons, and listening as much as possible. If children are interested in imitation, parents can use the situation, but it is completely gamification; After the age of 5, parents who know each other as soon as possible can tell their children some English story books, or try to make them follow the tape and remember the contents on the screen without asking them to really know the words and sentences on every page. At this stage, parents can cultivate their children's English listening and speaking ability, but the learning process is more casual. Preschool children are still not suitable for formal classroom learning.

Children who learn English early may not learn English well. However, children's pronunciation is generally formed before the age of 8, 12 years old. If children can get in touch with pure pronunciation from the beginning, the earlier they get in touch with English, the more conducive it is to improving the purity of pronunciation, improving the sensitivity and accuracy of language and reducing the problem of "accent".
