There are no specific Bible verses that mention baptism for babies. The practice of infant baptism is based on interpretations and traditions of different Christian denominations.
In most religious traditions, it is necessary to have a religious figure, such as a priest or minister, perform the baptism ceremony.

According to the Catholic Catechism, bishops, priests and deacons can perform baptisms. In extraordinary circumstances, however, anyone can perform a baptism. See http://www.usccb.org/catechism/text/pt2sect2.htm#1256
Methodists believe that one Baptism is enough. They believe that the effectiveness of Baptism is based on God's work in a person's life, not on that person's understanding of Baptism or ability to make a decision for Christ at the time of their baptism. That is also why Methodists allow infant Baptism.
