We do not baptize infants because baptism is a public confession of faith in obedience to Christ.
The clear teaching of Scripture is that all who believe in Jesus as Savior and Lord should be baptized in obedience to Him. The New Testament order is always the preaching of the gospel, faith in the gospel, then baptism. Never once is there an example of baptism preceding faith as the norm to be followed. There are also no examples or commands concerning the baptism of infants or unbelieving children of believing parents. Consider the following verses from Acts, noting the order of belief first then baptism.
Acts 2:41 ... those who had received his word were baptized ...
Acts 8:12 But when they believed Philip preaching the good news about the kingdom of God and the name of Jesus Christ, they were baptized, men and women alike.
Acts 8:36-38 And as they went along the road they came to some water; and the eunuch said, "Look! Water! What prevents me from being baptized?" And Philip said, "If you believe with all your heart, you may." And he answered and said, "I believe that Jesus Christ is the Son of God." And he ordered the chariot to stop; and they both went down into the water, Philip as well as the eunuch; and he baptized him.
We do dedicate babies and children each year in May. This is done by the family presenting the baby/child and the Pastor praying over the family and baby/child.
