Having a nebulizer is essential in my opinion, especially during cold and flu season. We stick with a simple saline nebulizer. It helps hydrate and soothe irritated airways. It also helps loosens mucus and makes coughs more productive. Always helps us kick coughs fast. This is not medical advice, just what works for us. flua rsv coldandfluseason LTKSeasonal LTKBaby LTKKids
