The first signs of the common cold in a baby are often:

• Nasal discharge that may be clear at first but might thicken and turn yellow or green

Other signs and symptoms of a common cold in a baby may include:

• Fever
• Sneezing
• Coughing
• Decreased appetite
• Irritability
• Difficulty sleeping
• Trouble nursing or taking a bottle due to nasal congestion

When to see a doctor

Your baby's immune system will need time to mature. If your baby has a cold with no complications, it should resolve within 10 to 14 days. Most colds are simply a nuisance. But it's important to take your baby's signs and symptoms seriously. If symptoms don't improve or if they worsen, it's time to talk to your doctor.

If your baby is younger than 3 months of age, call the doctor early in the illness. In newborns, it's especially important to make sure that a more serious illness isn't present, especially if your baby has a fever.

If your baby is 3 months old or older, call the doctor if your baby:

• Isn't wetting as many diapers as usual
• Has a temperature higher than 100.4 F (38 C)
• Seems to have ear pain or is unusually irritable
• Has red eyes or develops yellow or greenish eye discharge
• Has trouble breathing or wheezing
• Has a persistent cough
• Has thick, green nasal discharge for several days
• Has other signs or symptoms that worry you, such as an unusual or alarming cry or not waking up to eat

Seek medical help immediately if your baby:

• Refuses to nurse or accept fluids
• Coughs hard enough to cause vomiting or changes in skin color
• Coughs up blood-tinged mucus
• Has difficulty breathing or is bluish around the lips
• Has unusually low energy or sleepiness
