Don't go out and buy the OTC drops for plugged noses! Use things you have a home. This recipe works for all ages, my infant benefited a lot from it!
I have used a similar saline recipe, but the RN who recommended it to me emphasized the importance of using Kosher salt. Standard table salt is too harsh to be injested that way. Also, add a pinch of baking soda to cut down on the the burning sensation.
