C.K.
The Mall shops do not require certification classes for ear piercing, which is why you hear about a lot of trouble with infections after going there. Also they only offer two types of metal, and if there is a problem after they are not going to know how to properly resolve the issue. Piercing parlors, while a little creepy going into, should have their piercers getting these certifications, and are forced by law to provide a more sterile professional environment. They have a lot of metals to choose from and can give educated information on which metals to use to avoid infection. If infection results they also guarantee their work and will work with you to resolve the issue. Also studies have in fact shown that a piercing gun while faster is more painful than a needle. If the pediatrition can't do it in his office I'd personally take her to a professional piercer at a parlor where they also perform body piercings etc....
