Actress Hilary Duff pierced her baby's ears and sparked a heated debate about 'consent.'

Obviously baby tattoos are a big, fat no. But is it wrong for parents to pierce their babies' ears? This is a tricky one. I'm usually on the side of (in Chris Crocker voice) "LEAVE PARENTS ALONE"—especially moms, who deal with a tremendous amount of unnecessary shaming and criticism from society. And in the grand scheme of things, piercing your kid's ears seems like a relatively harmless thing to do. It's also common in many countries outside the U.S. On the other hand, I understand the argument against it. Piercings are painful and maybe not the best thing to do to a child who is too young to have any say in the matter. But then again, so is circumcision.

This issue has caused controversy in the past, like when Kylie Jenner decided to pierce Stormi's ears and everyone lost their minds. Well, people still have very strong feelings on the subject, apparently. The baby-ear-piercing controversy was reignited this week when singer and actor Hilary Duff shared an Instagram story showing her 8-month-old daughter Banks with newly-pierced ears.
