My daughter, 1 next week is having serve blocked nose, runny @ times. coughing which leads to vomiting @times and sneezing. what medication can i use?

The basics: The first months are troubled by their narrow nasal passages.Exposure to dust, fragrences, smoke & other irritants aggravates this.Baby tries to flush these out of the nose with mucous but this often ends as congestion & produces cough & sneezing. The best rx is washing out the nose with saline & suctioning the remainder. Eliminate irritants from babies environment & this will happen less.
