No. There's no reason to decorate a baby with jewelry and since it's her body, it should be a choice she makes WITH you when she is capable of making these decisions. This can be something she does with you at a later time as a mother-daughter bonding moment that allows her to feel a little more grown up, not something you do TO her as an infant. Ear-piercing is also painful and to subject a small baby to such pain for no reason is cruel. There's also the possibility of infection (especially when a piercing gun is involved) and a baby's immature immune system can be seriously compromised, leading to even worse results.
