One way you could interpret this is as a song of reincarnation.
However, I don't think that's the case. I believe the lyrics are about a parent's bewilderment towards their child's intelligence and personal identity from such a young age. Even if a child's a mere week old, he or she develops his or her own personality. By alluding towards reincarnation, I believe the lyrics are more set on comparing a young life to something as mystical and captivating as reincarnation, or any other religious/supernatural phenomenon itself.
