Actually the best and the only thing that would work is giving COLD BEVERAGES AND avoiding hot food for atleast 4 days Sips of cold milk or even ice creams can be given . This is because the lesions are there deep in the the throat and you can’t apply local Anesthetic creams deep in the throat!! The condition is self limiting and subsides in next 3-5 days

If the child is not able to eat/drink..need to admit You can give zytee lotion for oral ulcers

Consult with Pediatrician physically for further evaluation and treatment

Use bifolate mouth gel every 6 hourly 15 min before meals

If she is not able to eat anything, please give WHO ORS atleast. Take care of dehydration. Painful ulcers will heal in a week. Till that time you need to be extra cautious and apply orasore gel, honey / ghee frequently. Before giving food apply orasore gel 5-10 min prior.

Honey + turmeric Ghee + turmeric

U should visit a pediatrician and get an assessment done post which the dr will be in a position to guide u as per ur childs condition
