Many babies will have at least one cold during their first few months of life, according to MayoClinic.com, and the average baby will have 10 before their second birthday. Colds affect your baby's upper respiratory tract, causing a runny nose, nasal congestion and a sore throat. Unless pneumonia or another complication develops, colds are generally mild and clear up within 10 days. Babies under the age of 2 months, however, have very weak immune systems and so are more vulnerable to potentially serious complications. For this reason, it is crucial to report any cold symptoms in a newborn this young to a medical professional.
Take your baby's temperature every few hours using a rectal thermometer. Call your baby's pediatrician if her fever rises above 100.4 degrees F or fails to respond to over-the-counter fever reducers. The Mayo Clinic recommends giving acetaminophen to your baby to relieve fever.
Suction nasal congestion out of your 1-month old baby's nose using a bulb syringe. Squeeze the bulb of the syringe to force out any air, then insert the tip of the syringe about 1/4 inch into your baby's nostril. Slowly release the bulb to suction loose mucus from your baby's nose.
Use a humidifier to moisten the air inside your baby's room. This will ease congestion and improve sleep. Place the humidifier on a high, stable surface, out of the reach of other children. Turn off the humidifier if you notice signs of excess humidity, such as condensation on windows and furniture. Too much humidity encourages mold and bacterial growth.
Administer saline nose drops to each nostril every couple of hours. These drops will loosen mucus and soothe the inside of your baby's nose, thereby improving breathing and eating. Saline drops are available at most pharmacies.
Elevate your baby's head during sleep by placing a couple of pillows between the crib springs and head of the mattress. Baby Center cautions against propping your baby directly on pillows or placing objects under the crib legs. These methods can lead to suffocation or injury.
Monitor your baby's fluid intake to ensure she is drinking as much as usual. In most cases, additional fluid intake is not necessary. Adequate fluid intake will thin nasal congestion and prevent dehydration.
Alert your baby's pediatrician if symptoms of dehydration or a secondary infection develop. Dry diapers; a thick, green nasal discharge; or a cough that persists for longer than one week can all indicate the occurrence of potentially serious complications in a 1-month old baby. If your baby refuses to drink fluids, begins vomiting, coughs up bloody sputum or shows signs of breathing difficulties, take her to the emergency room.
