so from what i understand, speaking with simple terms (simply because i don't know well topic :)) - any living being, including human, starts with "blank brain" where a lot of interconnections exists and/or created easily. And since memories are really "state" of this very complex system, most of things/events remember-able simply blends and blurres during first few years of life.
For me this means two things - there is no way child will recall events from first couple years of his life. So there is no need to try to show new places, make him excited with particular event/thing. But in the same time, events happening in these early years affects brain (and whole body) development as a whole, so it is very important to make baby feel connected, safe, curious, etc.
Or even simpler - first couple years define "North/South/West/East" directions and then later brain develops within few "degrees" of this initial path.
