Madam If the fever is due to respiratory problems you can give normal diet

Hello there. I can understand your concern. His fever can be due to upper respiratory tract infection of viral etiology. You can continue crocin advance upto thrice a day but if it still doesn't resolve then you have to take him to a general physician. Viral issues are usually self contained and only supportive treatment is required. But if it's bacterial, then antibiotics can be required and for that you will have to be examined to find out if it's bacterial or viral. Consult with your family physician or any general physician in person for further help. Best regards
