I have two early childhood memories.
I remember a brief moment standing in my crib during the morning. And a dream I had in Pre-K where my pre -k teacher was the moon above me at night. Pretty early memory?
People might call BS on this, but I can recall the full layout of the home I lived in until I was 2 (to the shock of my family when I laid it all out). I have a memory from my first birthday as well. There are many people who have legitimate memories from very early on.
