Yes, we do know that and from a very early period. Press forward, as you are doing, and let no one stop you.
Thank you for that! I am sure it was a very early period. I always wondered why my childhood memories were few and far between. Just bits and pieces. Why some "traumatic" memories had no beginning or end. Fragments; like a fragmented brain. So much so, that one of the first things I said to my husband before we were married was; "I can't remember my childhood." Do you?
It was a nagging in the back of my head, telling me something was amiss. A constant nagging. I knew it wasn't just typical memories fading with time. It seemed like amnesia to me.
I will press forward and no one will stop me.
