Welcome to HCM,
Kids are born with very small adenoids
but as they grow the adenoids increases in size and they reach full size by approximately 12 years of age. After that growing period the adenoids start to shrink, but in some children it hypertrophies and causes nasal obstruction
, difficulty in breathing repeated ear and nose infection.
If the symptoms are mild you can continue with the medicines your doctor prescribed till your kid is asymptomatic.
If it becomes severe then discuss with your doctor regarding adenoidectomy
for removal of adenoids
