How do you get your mom to let you get your belly button pierced?

You have to give something to get something. Give her good grades, she might let you have your piercing. Give her consistent and properly done chores, she might let you have your piercing. If your mom cant be bargained with, leave the issue alone. Pushing and pushing her will only cause her to get irritated at you. If she wont give you consent, wait until you are old enough.
