They are not my sort of thing so I wouldn't do it, but I don't see it is that different from alot of things that babies have no choice in - some things I see babies wearing I think are ridiculous and detract from the baby, I don't really see ear piercing as any different - what they wear they have no choice in for a couple of years either - and I actually think that earrings don't really make them look more grown up unlike a lot of clothes - they don't have the same grown-up connotation to me that some makeup does - maybe I have that opinion because in some cultures is normal for children to have jewelry like earrings from babies.
