I had mine done at 10 months old and wore studs until I was around 14-15. I haven’t had my daughter’s ears pierced because my husband doesn’t agree with it, but I think each to their own! One massive plus is that really young kids won’t mess or play with their piercings, meaning less risk of infection etc. I had to watch all my friends wince with pain and have to have theirs removed in their teens, because they were constantly messing with them or tried to change their studs before they were healed...
