When is a good time to get ears pierced for a baby?

I don't believe in forcing your child to have pierced ears (that is piercing your babies ears before they are old enough to say no, mom, i don't want my ears pierced) but if you pierce them young then the less it will hurt them (the younger you are the less it will hurt). It would be better to wait because the piercing will change as your child grows and they may end up being uneven.
