I think claires accessories do baby piercing and they only use guns.
I walked past a Claires doing a baby's ears once and I felt really sad.
Thing is, is even if they come out there can be a tiny scar inside the lobe. I know lots of people who have never had piercings or tattoos, and being that I'm covered in 9 tatts and have had a great many piercings, I find that quite appealing, specially when that person has chosen that for themselves. I've never thought to ask anyone if they resent their parent(s) making the earrings choice for them like the parent(s) of the baby I saw, but I bet there's some out there who feel peeved that it wasn't their choice.
Your body is your own. all my tatts and piercings have been for me - Had 3 in my navel, and apart from during this pregnancy, have never got my tummy out for anyone. The piercings were just for me. So why a baby would have them done, I don't know.
