Hi, Welcome to HealthcareMagic Forum.
She might have developed Pneumonia due to Improper feeding habits. It is an inflammation of the lungs caused by infection usually by Bacteria or viruses. May be aspiration Pneumonia
in your Kid. Kindly don't worry as she will be in safe hands. She will require symptomatic treatment for cough
. She will be given antibiotics, it will take sometime for the Infection to subside and her symptoms will come down gradually. Once she recovers, Let her take Plenty of rest and Give her Plenty of fluids, mainly water. See to it that she completes the entire course of antibiotics. Take her for regular follow up.
I Wish her Good Health, Take Care.
