A. hi dear A nasal wash can help remove mucus from your child's nose. You can buy a saline spray at a drugstore or make one at home. To make one, use 1 cup (240 milliliters) of warm water, 1/2 teaspoon (3 grams) of salt, and a pinch of baking soda. Use gentle saline nasal sprays 3 to 4 times per day.
