Age for Ear Piercings?

Sarah
Hey moms, so have any of you pierced your girls' ears? Did they cry and for how long? I am thinking of waiting on piercing her ears until she can ask me to herself.. 3 years old? Everyone keeps telling me 3 mos is "the" age. I just feel that with so many vaccines the first year it's not worth the tears... But also think she'd look hella cute with earrings and ppl would stop asking if she's a girl or a boy. Thoughts?
