Question

My baby has suddenly started not talking much recently. He seems a bit dull and doesn’t smile as much. He’s also quite irritable. He’s very thin, doesn’t eat much, and stays up late at night, and doesn’t sleep well during the day. I’m worried he might be feeling unwell.

Answer

Based on the information you’ve provided, your baby’s symptoms may indicate some abnormal conditions. It could be a sign of a cold or possibly other physical discomforts. I suggest you take your baby to a nearby regular hospital’s pediatric department for a consultation and relevant examinations as soon as possible to determine the cause and receive treatment.
