Pl do not worry. Your doctor is doing best what he can do with allopathic medicine in given conditions. To my own such patients, I give herbal combo after the acute Phase of illness is over, to build immunity and resistance against recurring infection. This also cleans the respiratory tract of any minute congestion if any. Piper longum, Cyperus rotundus, Pistacia integerrima, Aconitum heterophyllum are four classic child friendly herbs dealing not only with pneumonia related problems but also detoxifies the intestines, controls lose motions, promotes appetite in small children. A classic combo of these mentioned in Ayurveda references is Balchaturbhadra CHOORNA. It s harmless, safe. Excess dose may cause gastritis. In our clinical career of three decades, many such children have got relief and cure with this combo. For any further needful, may consult through direct question or meet any ayurveda doctor near you. Hope it helps you.
