you can't unless your the age or over from where you don't need your parents permision to get a piercing and i would not pierce it yourself as known the belly button is more likely to get infected then any other piercings and mine is now but i got it done preoffesionally so don't even attempt to pierce it yourself you could do it wrong or anything so I suggest you just try talking to your mum and show her a video of somebody having it done and that is does not hurt and a few images which is really pretty which may change her mind hopefully and just try persuading her don't get mad if it does not work just wait you have plenty of time to get your belly button pierced.

As long as you have a parent with you, you only have to be older than 12. You have to be 18 without a parent though.
