Developmental retardation, with many types of manifestations; If children are mentally or linguistically retarded, their mother tongue should be the main language, and English enlightenment should not be carried out too early, otherwise it will easily lead to language barriers.

Prevention and treatment of language barriers

(1) The basic way for children to learn a language is imitation. Therefore, adults should talk to children more, train children to imitate adult's language pronunciation, encourage children to dare to speak, and learn to express their demands in language.

(2) Give more stimulation to let the children talk: for example, let the children call "mom". If the child doesn't call her mother, the mother should smile and nod. If they stop calling mom, they still smile and nod. Finally, if the child suddenly calls "mom", give a warm hug or kiss. In this way, children will experience the love they get by calling "mom" and stimulate their interest and enthusiasm in speaking.

(3) Let children have more contact with society and nature, and more contact with society and nature will enrich their lives, broaden their horizons and have a wide range of knowledge. Naturally, they have a request to speak. If combined with language training, children's language ability will be well developed accordingly.

(4) Mental factors: improve the living environment, so that children can get spiritual comfort and life care.
