Although I see no real harm in baptizing babies and infants, I also see no benefit. It is simply a religious rite that parents practice. I believe that most parents recognize that,ultimately, a child's faith must be his own.
In our church, we do not baptize infants, but we do practice infant dedication.This is a time when we bring our children in front of the church and commit to raising them according to Scriptural principles.We also believe that our children are a gift from God on loan to us. So the act of dedication is really , for us, a time to thank God for His gift and to recognize His ownership, not only of our child, but of us.As stated earlier, we believe that the child's relationship with God is, in the end, between him or her and God.
As far as free will is concerned, I do not believe that these practices have any real effect on the child's free will. The child will ultimately make his or her own choices. Our hope is that they will be guided by the principles by which they have been raised as they make those choices.
