Hi my child starts coughing in middle of the night for long time and it's dry cough. I think it's because of acid reflux. But I am giving his dinner 2 hours before sleep and also using extra pillows to lift his upper body. But coughing is coming almost 3 to 4 days a week now and during other times he is active and fine. I don't know what to do. Can you also give a ideal portion size for all meals of the day as suitable for south Indian style food. He is 4 years and 3 months old. This problem is occurring almost from 2 years. And I did not fed him junk or packed food from his childhood. I am worried a lot and not sure what to do. Tried jeera water, coconut water also but it doesn't work always.
