For you perhaps but please do not include all of Christianity in your views.
All the Protestant Reformers including Luther, Zwingli and Calvin held to infant baptism.
Baptism is one of the sacraments established by Christ (holy communion and baptism). Both are simply defined as covenant signs. Baptism is a sign and seal of God's covenant of grace with us and our children.
Baptism assures us that “as surely as water washes away dirt from the body, so certainly [Christ’s] blood and his Spirit wash away . . . all [our] sins”. In other words, baptism is the 'visible' word of God promising us that we are cleansed in Christ's blood, buried with him unto death and that we will rise with Him.
Reformed Christianity rejects the Roman Catholic view of baptism as unbiblical and sub-Christian because it replaces faith as the instrument of justification. In other word baptism does not save us.
Luther, Calvin, etc. teaching does Not mean Bible teachings without the Bible to back them up.

Sure, baptism does Not save - 1 Peter 3:21 - but the resurrection of Christ Jesus' shed blood " if " we......
The resurrection hope gives us the basis for faith (confidence) in order to dedicate oneself to God as Jesus did.
