You should discuss this with the Priest in the parish in which you want her to be baptized. If you are already Catholic, this should not be a big problem. If you are not, you may need to convert yourself. Chat with the priest and he'll take care of you. For the child there is no problem; because he does not understand any of this rituals. It's the parents because of their brain-washing that have problem. That's why the Amish don't baptize children. They wait until the child come of age where he now understand baptism And he can therefore opt to be baptized or reject it. I don't see any significance in baptism. Even Jesus himself did not baptize others. And if St. John, really believes that Jesus is god, then why did he continued with his ministry instead of following Jesus?
