I purchased these for my 2yr old. They were the perfect size for a toddler. I kept them on for about a week, then I removed them to give her ears some rest because she did complain about them being tugged by her shirts when getting dressed. Well, after I put them back on it seemed as if the security of the "lock" went weak. Needless to say she lost one that very same day. So don't waste your money...
