I don't hold to infant baptism. Honestly, I think there is a lot of scriptural gymnastics that have to happen in order to support the position. For instance, they like to use the circumstance of the Philippian jailer and how his entire house was baptized. Well, it also says in that particular passage in Acts that they were taught the gospel and they believed. The assumption is that "entire household" would have included any infants. Well, one would actually have to assume that there were babies in that household. That's eisegesis, in my opinion.
While I don't have them right at my fingertips to reference right now, I would point to all the passages of Scripture that teach that believers are to be baptized, and work from there.
I think this is a place where the Reformers erred. There were some brilliant men in the Reformation, and they got a lot of stuff right, but the sacraments of baptism and communion (which I refer to as ordinances), along with a lot of the eschatology is where I often differ in view with the Reformed tradition.

It's true that doctrine divides. It's also true that love unifies. The unity we have in the faith is rooted and grounded in truth and love. Remove truth (right theology and doctrine) from the mix and you have less than Biblical unity. Remove love and you have no unity. Love causes us to seek truth and share that truth with others so that we become more unified. God is truth, and as we are more acquainted with His truth, the closer we are to Him, and the closer we become to each other
