What can i give my newborn daughter who is 5 weeks old and has a cold, nose is stuffy, she's coughing and sneezing?

Nasal saline: Nasal saline followed by suctioning is the only thing that is recommended at this age. There is nothing safe to give by mouth.

Doubt it's a cold: The first months are troubled by narrow nasal passages & exposure to dust, fragrences, smoke & other irritants aggravate this.Baby tries to flush these out of the nose with mucous but this often ends as congestion & produces rattling with breathing. The best rx is washing out the nose with saline & suctioning the remainder. Eliminate irritants from babies environment & this will happen less.
