An increase in mucus production can be caused by a variety of things, from the common cold to allergies. According to the Kids Health website, certain conditions, such as dry air or exposure to cigarette smoke, can lower the immune system, making children more susceptible to illnesses that promote mucus and congestion. Fortunately, there are a variety of ways to soothe your child's symptoms and help eliminate mucus.
Squeeze a few drops of saline into your child's nose approximately four times a day. The Parents website explains that this can help move the mucus trapped in the nose, making it easier to blow out.
Steam up the bathroom with a hot shower or bath. According to the Kids Health website, this can help open up the nasal passage, making it easier for your child to breathe.
Give your child plenty of fluids to help loosen up and dispel mucus in the throat and nose. Provide clear liquids such as flat soda, watered-down fruit juice and sports drinks. These types of drinks are more easily absorbed than just water.
Provide chicken soup. The Kids Health website explains that it contains cysteine, an amino acid that helps regulate the white cells that cause congestion.
