A common cold is a viral infection of the nose and throat (upper respiratory tract). Babies are specially likely to get the common cold, in part because they are around older children and also because they have not yet developed immunity to many common infections.
Within the first year of life, most babies have 6 to 8 colds. It is easily passed to others, especially within homes and classrooms.

Symptoms

Symptoms usually appear one to three days after exposure to a cold-causing virus. Signs and symptoms include:
• Runny or stuffy nose (congested) causing difficulty breathing from your nose
• Sore throat
• Cough
• Congestion
• Difficulty sleeping, trouble nursing or taking a bottle
• Sneezing
• Low-grade fever
Otomar benefits

Nasal saline irrigation may be helpful for relief from obstructive secretions, particularly in young children. Children using nasal saline wash showed faster resolution of symptoms and a possible preventive effect in reducing the number of upper respiratory tract infections with regular use.
Overall children tolerate nasal saline spray well.
The best method for delivery of nasal saline is through spray multiple times daily.
