Breathe right strips for ears?

Hi, everyone. I found the info on using breathe right strips for ears really interesting. It looks easy and I think I am going to try it on my 5 1/2mo Bella. Her ears stand up, but her tips are flopped. You guys are all saying its not too late, so i want to try. I saw your post with pic and explanation, easy enough. What I need clarified is how long do you keep the strip on the ear without causing any problems. like do I change the strip once a week? Dont adhesives breakdown skin if used long term. Or does she wear them part of the day? If someone can help me I would appreciate it. thanks:emo8:
