But even so, if the holes do close, you can still see them.
I didn't have my ears pierced until I was 26, only to find out I can't wear earrings of any kind. Many times I attempted yet another try. The last time was 9 years ago. Although the holes are closed, you can still see them and it looks like I have pierced ears. People often ask me why I don't wear earrings since my ears are pierced.
As for babies with pierced ears, I think they should be old enough to make that decision.
