I'm not an expert by any means, but I believe that Catholic Church teaches that if you are not baptized you can not go to heaven, only purgatory.
I believe that most Protestant's believe something similar in regards to being "saved". I'm not sure how young children fair in the Protestant version of Christianity? Perhaps it differs from sect to sect?
So, I'm wondering if your comment is factually accurate according to beleivers in various Christian faiths.
I am not Catholic and do not beleive that..
In actually a baptized infant is not a Christian unless when they become mature exercise saving faith in Jesus Christ. Their baptism is not the baptism taught in God’s word and it signifies a false concept that baptism conveys salvation and that sprinkling an infant initiates it into salvation.
The New Testament is clear that God’s word says to “Repent and be baptized.” (Acts 2:38) Infants cannot repent because they have no ability to understand sin.
Infant baptism forces on a child something they cannot understand, comprehend, or accept, and that is repentance for sin and belief and trust in Jesus Christ. Most of all....infant baptism is not found in God’s word. The verses such as Acts 16:30-32 specifically state that those who were baptized believed. They exercised saving faith in Jesus Christ and afterwards were baptized. The passages does not state any infants were present, nor were baptized.

Growing up in a Southern Baptist home we were told that the “age of accountability” was twelve. Don’t ask me where that comes from, I don’t really know, but it seemed to be accepted without question.
