Hi my baby is 4 months old now, she is having dry cough and sneezing. Please help me how to cure it

A. Breast Milk There is no remedy or cure that is greater than the only natural food for a newborn human – the breast milk. It works as a remedy for any infections in babies who are six months of age or even older. Regular feeds also help calm a cranky baby who does not understand anything and gains comfort only from his mother’s touch.
