Why 
                do some churches baptize babies, while others only dedicate them? 
                
              This 
                difference in practice goes back to the early days of Protestant 
                Reformation. The tradition up to then had been to baptize at any 
                age, including infancy. In view of high infant mortality, the 
                earlier the better, many believed. 
              The 
                emerging Baptist tradition, however, argued that the sacrament 
                of initiation into Christian community needed to be a conscious 
                decision made at an age of maturity, much like the Bar Mitzvah 
                of Judaism. For that reason, they delayed baptism until around 
                the age of 12. At the same time, they wanted to affirm a newborn 
                baby and to engage the congregation in caring for that child. 
                Hence, the ritual of dedication. 
              Some 
                reformation churches, such as the Episcopal, Methodist, Lutheran 
                and Presbyterian churches, continue to practice infant baptism, 
                although it isn't required and the decision isn't accompanied 
                by any medieval superstition about an unbaptized child's going 
                to hell if they die young. Some conservative churches have adopted 
                the Baptist tradition, known as “believer's baptism.”
              As 
                with every other argument in Christianity, each side has plenty 
                of Scripture and Tradition to support its views.
