Baby congestion can be treated with a few simple remedies that can help make your baby more comfortable. One of the safest and most effective ways to help clear a babys congestion is with a saline (salt water) spray or nose drops. These products are available without a prescription. You can place two drops in each nostril to loosen the mucus inside, and then use a suction bulb immediately afterward to withdraw the saline and mucus. You can also try using a cool-mist vaporizer or humidifier in your babys room to add moisture to the air, which can help clear their stuffy nose. Additionally, gentle taps on your babys back can help ease chest congestion. Its important to note that if your baby has other symptoms, especially a fever and thick, yellow mucus, you should call your pediatrician as soon as possible.
