This is a simplistic view of God and assumes that a little water can manipulate God so that he won't send a perfectly innocent baby to hell. If I were God, I'd be offended. The child may show up in Sunday school irregularly, get confirmed, get married in the church and ultimately be buried from the church. We call those Hatch, Match and Dispatch Christians. I don't think that child ever got what is meant by being baptized.
Baptism is ritual drowning.
It signifies dying to a life of sin and being born again to a life in Christ Jesus. But many people have as little understanding of baptism as the drunk who happened upon a Baptist ceremony at the river. When the preacher asked him if he'd found Jesus, the drunk responded, no. So the preacher grabbed him and put him under the water. So we have being caught as fish as a violent metaphor, being baptized as a violent metaphor, crucifixion as a violent act Jesus Christ has undergone for us, we're in a violent religion.
