Thanks for writing to health care magic.
Your child requires urgent medical attention. This is because he is feeling drowsy and lethargic which is one of the danger signs.
A parent should know that if a kid has lethargy
, poor feeding, vomiting
or loss of consciousness
then he should be taken to the doctor immediately.
Your doctor will get a throat swab for culture and start him on antibiotics if required.
Hope this helps.
