my mum got mine pierced when I was 9 months old because she got sick of people asking about her "little boy'' even when dressed in the most flowery pink outfit! My holes are uneven and a bit high (but that also means i can wear huge dangling earings ). I occassionally get an infeciton from them, but find it's usually from buying a cheap pair of earrings. in general though I like having them pierced.
As a girl, i thinnk i just had small studs in. I don't really remember 'wearing' earrings til I was a teen. I then wanted a 2nd hole and paid for it myself when I was 15. OMG it hurt so bad and always got infected so i let it close up after about a year.
Now i wear a pair of diamond studs my dh bought me every day
However, i won't be getting our little girl's ears done til she is probably 13, if she wants it.
my reason ... Lazy mummy. Can't be bothered paying for it, cleaning them, etc etc for the next 13 years when she can do it herself when they are done! and pay for her own earrings too!!!
not for or against it in babies. I think it's personal choice.
