A baby does not make the choice and therefore the babies are not responsible or authors of their own death.
You said that humans make the choice to die by eating incorrect foods. There are many humans that die having not eaten correct or incorrect foods. Now you are saying that very young humans fall under a different rule set.
Who made the choice for an infant to die a natural death? You say that there is no such thing as a natural death but then someone must be responsible for the death of a baby.
At what point do humans gain the ability to not die a natural death by eating correct foods?
When do the rules change and how did you find out about this change? If there is an experiment, can you provide the links?
