My kid has a chronic respiratory disease and the doc told me to always keep an eye on her breathing. At first I just heard her breath with my bare ears but it was not enough. I wanted to be more thorough with my daughter's health and I got it. Now I can check on her breathing sound everyday, I am much less worried.
