A few factors put infants at higher risk of common colds.

  • Immature immune systems. Infants are, by nature, at risk of common colds because they haven't yet been exposed to or developed resistance to most of the viruses that cause them.
  • Exposure to other children. Infants tend to spend lots of time with other children, and children aren't always careful about washing their hands and covering their coughs and sneezes. So if your baby is in child care or has an older, school-age brother or sister in the house, your baby may have a higher risk of catching a cold.
  • Time of year. Both children and adults are more susceptible to colds in fall and winter. Children are in school and most people are spending a lot of time indoors, which can make germs easier to spread from person to person.
