Most often, you can treat an older baby's cold at home. To make your baby as comfortable as possible, try some of these suggestions:

Offer plenty of fluids. Liquids are important to avoid dehydration. Formula or breast milk is the best choice. Encourage your baby to take in the usual amount of fluids. Extra fluids aren't necessary. If you're breastfeeding your baby, keep it up. Breast milk offers extra protection from cold-causing germs.
Suction your baby's nose. Keep your baby's nasal passages clear with a rubber-bulb syringe. Squeeze the bulb syringe to expel the air. Then insert the tip of the bulb about 1/4 to 1/2 inch (about 6 to 12 millimeters) into your baby's nostril, pointing toward the back and side of the nose.

Release the bulb, holding it in place while it suctions the mucus from your baby's nose. Remove the syringe from your baby's nostril and empty the contents onto a tissue by squeezing the bulb rapidly while holding the tip down. Repeat as often as needed for each nostril. Clean the bulb syringe with soap and water.
Try nasal saline drops. Your baby's doctor may recommend saline nasal drops to moisten nasal passages and loosen thick nasal mucus. Look for these OTC drops in your local pharmacy. Apply saline nasal drops, wait for a short period, and then use a suction bulb to draw mucus out of each nostril.
Moisten the air. Running a cool-water humidifier in your baby's room can ease nasal congestion. Change the water daily and follow the manufacturer's instructions for cleaning the unit.
