My son, Jonathan, suffered with chronic ear infections. During the 8 months that he had tubes in his ears, he only had 4 ear infections. Just over 1 month ago, I was introduced to Kids Need Us Website, where I discovered that the plug-in air fresheners that I had all over my home were giving off formaldehyde which was a possible major cause of chronic ear infections in children. I removed all of those plug-in air fresheners from my home. My son has not had an ear infection since that time. If there is an alternative which makes my house smell just as good and my son is no longer sick, this is definitely worth it to me.
