the newborn does not know-" if it exists, it doesn't even realize yet that it doesn't know. it is bombarded by so many fresh new smells sounds, auric-like sight. and a brain is unable to process, let alone have storage sections set up yet. to organize it. with this bombardment, it doesn't have thought yet. nor reflections. it is also apparent, that this is true cause shortly after its infant/toddler stages, it struggles with knowing the difference between itself and its mother/main parent. its not till about 3-4ish when it can really grasp it is not its parent, and that it exists in some manner by itself.
