The baby doesn't talk much.

A baby's limited speech may be related to personality, or could result from factors such as a short lingual frenulum or hearing impairment. There is no standard treatment; instead, targeted therapy should be based on the specific underlying cause. Detailed analysis is as follows:

1. Personality

If a baby has a more introverted personality, they may tend not to speak much and prefer quiet environments. Parents can help by increasing communication with the baby and taking them to participate in outdoor activities, which may assist in gradually improving their communicativeness.

2. Short Lingual Frenulum

A short lingual frenulum can restrict the movement of the baby's tongue, affecting normal speech and eating. Parents should take the baby to the hospital for medical evaluation. Treatment may involve surgery, such as a lingual frenulotomy.

3. Hearing Impairment

This refers to organic or functional abnormalities in the auditory system involving sound conduction, perception, or any level of the auditory central pathways. When a baby has hearing impairment, they may fail to hear surrounding sounds or others' speech, which affects normal communication. Treatment may include medications such as mecobalamin tablets, vitamin B1 tablets, or prednisolone acetate tablets, as prescribed by a doctor. In some cases, hearing aids or surgical intervention may also be necessary.

In addition to the above factors, conditions such as autism spectrum disorder should also be considered. Parents should promptly take the child to the hospital for professional evaluation and diagnosis.
