In the hospital, sometimes you can see some young mothers and fathers bring their children to consult: “My baby is two years old, why does he only call out mommy and daddy, he understands everything he is asked, but he just refuses to talk, just gestures with his hands.” “My baby usually looks quite resourceful, hearing and intelligence tests are no problem, just not much talking, only call mommy and daddy grandparents.” …… Language is a tool for communicating ideas, expressing the mind and emotions with people acquired through repeated learning and practice in life practice. Delayed language development in children is caused by a variety of reasons, the child’s verbal ability or language comprehension significantly lags behind the development level of normal children of the same age and gender. Delayed language not only affects children’s cognitive development, but also affects their emotional, personality and interpersonal development, and can even lead to psychological abnormalities in children. So, what are the reasons that can make these babies’ language development lag behind that of children of the same age? Possible disease 1: abnormal hearing organs Children learn to speak, first of all, they must be able to hear the outside world, in order to gradually imitate and learn to speak. If the auditory organs are abnormal and cannot hear the outside world, then it is impossible to imitate speech, and eventually it will not speak, which becomes the so-called deaf children. Many deaf babies look healthy when they are born, but in fact, they are likely to have a hearing impairment in their mother’s womb, and most of these babies do not speak until they are 2 to 3 years old, and only then do they come to the attention of their parents, but by this time they have already missed the best time for early intervention. Therefore, it is very important to do a good job of newborn hearing screening. Newborn hearing screening can detect deaf babies at an early stage, and if early intervention and rehabilitation are given after detection, the impact on language and cognitive development can be reduced to a certain extent, and the development of language can even be brought close to that of normal children. Newborn hearing screening is a simple, objective and quick way to screen out newborn babies who may have hearing impairment and to further confirm the diagnosis and follow-up. According to the regulations, newborns who do not pass the initial screening should be re-screened in both ears within 42 days, and those who do not pass the re-screening should be referred to a hearing disorder clinic designated by the provincial health administration within 3 months of birth for further diagnosis. However, parents should not panic too much when they are told that their baby did not pass the hearing screening, but should actively cooperate with the doctor for re-screening, referral and intervention treatment. In addition to congenital deafness, some acquired factors such as drug damage (streptomycin) and inflammation (otitis media) may also cause hearing impairment in babies and eventually hinder early language development in children. Possible disease 2: Abnormal brain development Non-progressive brain injury due to various causes, such as cerebral palsy, mainly manifests as central motor disorders and postural abnormalities, often accompanied by language and intellectual impairment. In the past, cerebral palsy was thought to be incurable. With the continuous development of rehabilitation medicine, it is found that cerebral palsy is actually treatable, especially early diagnosis, early intervention and treatment can normalize many children with cerebral palsy. If early rehabilitation and early intervention can be applied in time during this period, it can promote the potential of high-risk newborns who may develop sequelae of brain injury, prevent or reduce the occurrence of their disabilities, and make their development catch up with normal children. Prematurity, low birth weight, asphyxia, hyperbilirubinemia, multiple births, primiparous births at advanced maternal age, pre-eclampsia, infection, neonatal convulsions, and intracranial hemorrhage are high-risk factors for brain tissue injury. Therefore, active maternal pregnancy and perinatal health care, prevention of preterm birth, obstructed labor and asphyxia are important measures to reduce pediatric brain injury. Possible disease 3: Abnormalities in the organ of speech The organ of speech includes the lungs, larynx, face, mouth muscles, hard palate, palatopharyngeal muscles, tongue, jaw, etc. Due to abnormalities in the organ of speech, it may also cause language development disorders. This is characterized by the baby’s ability to articulate, but the speech is very unclear, such as a nasal overtone or a soft nasal overtone, or a nasal overtone in children with cleft palate or submucous palate. Almost all children with dysarthria have some degree of lingual-labial dyskinesia, which can distort, displace, or make unintelligible the sounds produced. Therefore, children with dysarthria should undergo surgery as early as possible and go to a regular rehabilitation training institution for systematic and standardized tongue and lip movement training, articulation training and phonetic discrimination training in order to correct dysarthria early. Some children may stutter when they are young, and the stuttering will gradually improve or disappear as they grow older, but only a few may persist into adulthood. Some children with stuttering have poor fluency and poor word-to-word skills due to late speech, and the repetition and prolongation of the last word. However, if parents are overly concerned and nervous, they may put a lot of psychological burden on the child, which may aggravate the stuttering or prolong the correction process. Therefore, it is important to treat children who stutter correctly, not to over-correct their speech, avoid punishing, discriminating, teasing, ridiculing or deliberately imitating the child’s stuttering, and to encourage the child to participate in group activities and exercises. Possible disease 4: Autism Autism, also called autism, is a neurological developmental disorder whose causes may be related to genes and heredity. Children with autism generally have normal hearing, but they refuse to speak or talk much. Some can say something, but it is often some repetitive language, parroting language, talking to themselves, or some active language that can be communicated to people that is not understandable at all. Therefore, if you find that your baby has delayed language development and is accompanied by social interaction disorders and stereotyped behaviors, you should promptly take your baby to the hospital and ask the appropriate specialist to confirm the diagnosis in order to detect children with autism early and intervene early in order to promote rehabilitation. Language stimulation – an important condition for children’s language development In addition to the four disease factors mentioned above, a good language learning environment is also a facilitating factor for babies to speak early. A person who can speak is not born with it. The formation of language also requires a good language environment – language stimulation – which is an important condition for children’s language development. Children lack real effective language stimulation, or no repeated language reinforcement, learning to speak will naturally be one step slower than others, so parents should grasp the baby language stimulation of several important links: First, in the infant 2, 3 months “babbling” period, at first, the baby will unconsciously sound “If adults can also give him a little response, the infant will feel excited and will repeat the sound, these sound stimulation can exercise the infant’s language hearing ability. At the age of 7 or 8 months, infants are able to understand the sound of certain words spoken by adults. Therefore, parents must lose no time in communicating with their infants while linking a word in speech with something specific. Since adults always accompany their own actions when using words, infants will gradually begin to imitate adults’ word sounds as they imitate their actions. Finally, after 1 week of age, babies start to enter the formal language learning stage. During this period, parents should create more opportunities for their children to learn and train, especially to let them have more contact with life and society, and when they have seen more and known more, they will naturally want to express their meaning and have the requirement to speak, and will be happy to talk with their parents, family members and peers to exchange what they have seen and heard. In addition, when parents are listening, they should also lose no time to help him master the language vocabulary and language expression skills, in this communication process, the child’s language expression ability can be developed very quickly.
