Patient's question:
My baby is four months and ten days old and can't make any sounds when laughing, nor does she have tears. The health check was normal (tracheal cartilage underdevelopment). She coos and talks to adults (not often) and laughs when tickled, but without making any sound. What could be the reason?Doctor's answer:
In this case, as long as the child has a smiling expression and movement, it proves that they can smile, even if they don't make a sound. It may be caused by a lack of vitamins and trace elements in the baby's body. You can supplement nutrition by eating more vegetables like carrots and greens, and taking oral glucose. During daily conversations, guide them to engage in language exchange. If any abnormal conditions are observed, it is recommended to revisit the hospital's ophthalmology department for follow-up.
