Id reccomend you to go a professional piercing place, where they usually do tattoos too.
My first set was done by my aunty at 9 months old, she did it with out telling my parents.
My second set was done at 3 years old but they got infected,
My 3rd set was done at 5 years old but i had to take them out because my school didnt allow them in london.
My 4th set was done in italy by a jewler and i was really happy and kept them, then i got my 2nd hole was done when my cat died and my mother tried to cheer me up
my 3rd hole my mother didnt even realise for 3 years because i went out one day and got it done, and for school we were only allowed one piercing in so my mother never realised
then for my 16th birthday i got my nose done, had that for over a year and then i took it out, and while i was 16 i got my belly button pierced at this bong place in Melbourne (called smokey dreams) and my piercer was soo good and soo nice
After i came back from my holiday in australia at 16 (i went by my self)
I showed my mum, my dad laughed and my mother was appaled hahaha
