Patient’s description: The baby is two weeks old and still can’t talk, he only says some simple mommy and daddy, goodbye, and only occasionally, and the sound he says is still true, but he doesn’t say anything when he is asked to, and most of the time he doesn’t talk. Hope to provide help: Is this condition of the baby autism, how to guide the baby to talk? Expert reply: The baby is two weeks old and still only says simple mommy and daddy, and only occasionally, so he should be behind in his language development. But it depends on what the cause of the developmental lag is? Is there a problem with the language environment? Is there a delay in brain development? Or is it a genetic delay in speech? Or a hearing problem? It is recommended to see a pediatrician for further analysis. If necessary, a developmental exam may be required. Regarding how to guide your baby to speak, the most important thing is to help your baby establish a good language environment. Parents must not be in a hurry, as there is a pre-language stage before language emerges. The most important thing in the pre-language stage is to let your baby listen more. Instill a variety of language in your baby’s ears in different ways, simply and clearly. The simpler the form of language, the better, and preferably in as few languages as possible, starting with the most commonly used names of people and objects, and teaching things to the baby with exaggerated tones to attract the baby’s attention. Rome was not built in a day, and your baby’s language environment must be created consistently.
