Question about ear piercing

This has been a constant source of problems with our FD as well. She really wants her ears pierced and her mom is dead set against it. OF COURSE, non custodial dad who lives in another state uses every opportunity he can to tell her that he fully supports her decision to have her ears pierced. GRR! We were told regardless it's the parent's decision. This is one of those times CW will not override. (and rightly so IMO.)
