Why do babies get so many colds?

Why do babies get so many colds?

There are more than 100 different cold viruses. Babies have not yet built up their immune system to fight all of these germs. Before turning 2 years old, a baby can get as many as 8 to 10 colds a year. Most colds are seen in the fall and winter. That’s because children are indoors more and in close contact with other babies and caregivers who may have the cold virus.
