While I would agree that children are under the protection of guardian angels, I do not see how that necessarily negates their original sin. At this point, we would have to delve into the semantics and specifics of the practice of baptism and what it entails in order to find common ground in it's utility. In order for baptism to be effective, the child must fully understand what it is that they are being cleansed of, and what this means in regards to their accountability for sin from that day forth. This must be powerful enough to drive the point home with them, without causing them any emotional trauma or pain. In other words, it should be a positive reinforcing experience, and not a negative one.
Quoting: Rising Son what is then the original sin that you as a soul are guilty of, dear brother?
the soul that indwells me is of the pure nature of universal love.
and it entered my body through the portal opened through the pure love between my parents.
it was fed in the gestation process with pure love.
it is sinless. as any other heveanly soul.
the concept of original sin makes sense only to the karma of blood/matter/generation/animal soul
the Son of Man, or the Heavenly Man, or Human proper knows no Sin because it is made in the image of god.
it only has to overcome the karma of flesh which may be easier or harder depending on case
