is it safe to use saline moisturizer to clean the mucus from her nose ? she has normal cold, it gets hard for her to breath at times when the nose is filled with flu mucus.

A. definitely you can use saline drops as well as saline nasal spray because it is just simple salt water which does not cause any type of side effects to the child and can be used again and again and will help in decreasing both cough and cold and nasal obstruction and mucus clearance
