What could be the reason for a nine-month-old baby having slightly enlarged tonsils?

Patient's question:

No

Doctor's answer:

tonsillitis is an acute infection of the upper respiratory tract, a bacterial infection, a non-specific acute inflammation of the palatine tonsils, often accompanied by acute inflammation of varying severity of the pharyngeal mucosa and pharyngeal lymphatic ring. Intravenous administration of antibiotics can be considered for treatment.
