There are many reasons for delayed language development, usually affecting children’s speech are hearing impairment, abnormal articulation organs, mental retardation, autism (autism), language environment (intergenerational people with children or nannies do not love to talk to babies), psychological problems, etc. If there is no problem with the above mentioned aspects of the baby, if the child still does not speak when it is time to speak, then it is recommended that the mother can take the child to a professional institution for a child language test. Through these tests, it is possible to find out whether the child’s language development age matches the actual age. If parents find that their child’s language development age does not match their actual age, they should intervene early, in addition to going to a professional institution for targeted treatment, the child’s daily training at home is also very important. Parents training baby speech principles 1, and children to speak concise language, slow, focused, not complicated, each word to say clearly. 2, expressions, movements exaggerated and interesting, interact with the child, try to play the way. 3, parents do more demonstrations, you can use objects, pictures, actions, expressions, words to guide the child to speak. 4, do not do negative hints to the child, especially in front of strangers do not say my baby does not like to talk, etc., so the baby will not open up. Children have shortcomings and mistakes, do not point out in front of strangers, should respect the baby, more praise, praise the child, give the child confidence, encourage the child to talk more, more positive hints to the child, even if he only said a word, but also to praise him. 5, anytime and anywhere to seize every opportunity to train the child’s language skills, such as when the child is looking at an object or participate in an activity, or in the game, in the music, on the road, in the park …… are good opportunities to train children to speak, tell the baby “grandpa is crossing the road, grandma is watering the flowers, this car is going so fast”, This car is going so fast” and so on. 6. Take time to read with your child every day. Parents should fix a time every day to hold the baby in their arms, while reading picture books with him and reading to him. These standardized, rhythmic and beautiful language will form an impression in the baby’s brain, and over time, continue to penetrate, although the baby can not fully understand the meaning, but can help the baby gradually establish a good taste in language. For smaller babies, parents can repeat the words that appear repeatedly in the book, for older babies can repeat a sentence in the book, and then older babies can let him repeat the story in the book, so as to practice the baby’s ability to listen and language skills. The time does not have to be too long, ten minutes a day can be, but must be insisted on. 7, let the baby more contact with small partners, to develop the desire to talk with small partners. 8, when the baby is talking, parents do not interrupt, let him finish his own words. If there is a fast-talking mother who always speaks for the baby, the baby may never be good at expressing himself. 9.Create a good language environment for your baby. At home, mothers and fathers try to speak more often and let the baby listen to how others express themselves, knowing that babies progress by imitation and learning. Most parents are always concerned about their children’s height, weight and learning, but rarely about their children’s psychological development, which is worthy of their attention. 1 to 2 years old is a critical period for children’s language development, and most children with language disorders are discovered during this period. If your child still does not speak by the age of two, or only speaks simple words and lacks communicative language, it is important to take your child to the hospital immediately for a professional diagnosis.
