although infants may indeed be regenerate, they have not made a credible profession of faith. Therefore, it would seem to be rash to include them within the New Covenant before being reasonably convinced that they actually do possess faith in God.
If this is the heart of your concern, my way of thinking responds with the following points:
1. When I see a church kid, I do NOT begin with the assumption that he is unproven or more likely than any of the rest of us to deny Christ some day. Rather, I begin with the assumption that God has put this child into his church and is at work in him. I'm expectant about seeing faith in that child, because I know God is good. I don't make assumptions about God's timing (the child may have no faith yet), but neither do I assume that my faith is necessarily stronger than his. Childlike faith is affirmed many times in Scripture, and it would be wrong of me to assume that just because a child is still a child he is to be suspected as a future apostate in a way that I am not.
2. Baptism is not an earned badge of honor, either for kids or adults, as if we wait to see signs of growth in a believer and then baptize him because he's proven himself fit. Rather, every instance of baptism in Scripture comes at the very beginning of the Christian life, before growth and discipleship. If a child is in the church and is being discipled, he should be baptized.
3. Baptism not only begins the life of discipleship; it is an important sign from God that ordinarily aids in the discipleship process. I can't teach a kid to love God while at the same time treating him as if he's a unproven heathen whom, unless the kid proves otherwise, God is likely to hate for all eternity. To teach a kid to love God and to disciple that kid in faith, I need to have some expectation that God loves that kid and is at work in the kid's life. To do otherwise is to attempt discipleship without grace, a fatal error.
4. Be careful not to make too much of the New Covenant, as if what God instructed before the cross doesn't really count today. I don't see any scriptural evidence that in this era we are instructed to more rigorously "vet" those who would enter the covenant community than God's people did in Old Testament times. If anything, the main thrust of Scripture is that now the gates are flung open and all may come to Jesus. It would seem strange if under the New Covenant God's community is more open than it used to be for adults, but now has new restrictions that didn't exist before for the children of God's people.
Anyway, that's how this paedobaptist thinks. I hope it helps you. I do much work with kids at my Baptist church, so obviously I don't think these points are absolute essentials for cooperation with others. And I find with most Baptists that as they understand where I'm coming from, they find the position is not as unthinkable as they once thought.
