I think the doctrine of Original Sin is still canonical to all branches of Christianity. Every attempt to redefine newborn children as sinless has been heretical. Calvinists are especially big on babies' depravity, IIRC.

The only exception is the Mormons. Of course, other Christians may well see Pearl of Great Price as heretical, but there you have it. They are actually the sanest on this topic.

Wikipedia also says:

Furthermore, Mormons hold that little children are incapable of committing sin and, as such, have no need of (saving) baptism until age eight when they can discern right from wrong, and are thus capable of sin and can be held accountable. Little children who die before reaching the age of accountability (even though they are unbaptized) are automatic heirs of salvation and are saved in the Celestial Kingdom of God through the atonement of Jesus Christ.

Those who are incapable of understanding right from wrong, such as mentally handicapped persons, are also saved under the atonement of Jesus Christ without baptism.
