What is Colds, Coughs and Other Viral Infections in Children?
Young children typically catch several colds and viral infections each year, since their immune systems are still building up resistance to common viruses. Symptoms usually include a runny or blocked nose, cough, mild fever, and sometimes a sore throat, and typically clear up within a week to ten days without needing specific treatment.
While frequent, these infections are a normal part of childhood immune development, especially once children start mixing with others at childcare or school.

- 2Use saline nasal drops.These can help clear a blocked nose, especially before feeds or sleep.
- 3Raise the head of the cot or bed slightly.This can ease breathing and coughing at night — never use pillows for babies under 12 months.

- 5Let your child rest.Extra rest supports the immune system while it fights off the virus.

BarnMD Bottom Line
Frequent colds are a normal part of early childhood as the immune system builds resistance to common viruses.
Difficulty breathing or a blue tinge to the lips or skin should always prompt emergency care, regardless of how mild the cold seemed at first.
