According to Reformed Theology, how can one justify infant baptism?

I have read the entire Westminster Confession of faith before; and I agree with pretty much everything except for the infant baptism section: > 4. Not only those that do actually profess faith in and obedience unto Christ, but also the infants of one, or both, believing parents, are > to be baptized. The scripture proofs they provide are as follows: Mark 16:15-16, Acts 8:37-38, Genesis 17:7,9- Galatians 3:9,14 - Colossians 2:11-12, Acts 2:38-39, Romans 4:11-12, 1 Corinthians 7:14, Matthew 28:19, Mark 10:13-16. **Q: According to reformed theology, is the Westminster confession of faith faithful to scripture for their assertion of infant baptism? Why or why not?**
