(I've revised this to try to be more concilliatory and show my reasoning from Scripture more. Thanks for comments that pointed out that my post had not been very humble. I'm attempting to be provocative (I genuinely think this is an important topic where we may be putting unecessary burdens on children). I hope also to be gracious.)
The age at which to baptize a child who professes faith in Christ can be a tricky issue for many churches. And depending on how a church handles the question, other issues can arise further down the road, such as the “rebaptism” of those who come to doubt the genuineness of their childhood profession of faith.
