From my understanding the average human's memories of life before they were 10 is limited to stuff like their favorite teacher(s), pets, exciting events. My cousin was 8 when he got to do Make A Wish. He's 17 now and all he remembers was the RV and aquadog we went on.

I have the same problem only backwards, I remember most of my childhood from the age of 3 to 10 then from 11 - 19 I only have a few distinct memories like climbing a bolder on the ranch we were renting and my play house which was an abandoned boat that was falling apart and rotting out and a huge rat the size of a cat lived on it along with a snake and field mice and wasps. It was a great place. Now I have hardly any memories of my adult life. I sort of remember moving here 4 years ago but not really. I don't know when we moved to this house though I think maybe it was three years ago. I "know" my bedroom was the biggest one but then I moved to the smallest one cause there was snow coming in my old room through a hole under a window. But I don't remember how I got my things moved from one room to the other. I don't remember exactly how I started working and the memories of all my jobs are hazy I know what I did but I don't remember actually doing any of it. I don't remember if I ate or not. I don't remember anything about last week at all. I'm not sure what causes this but trust me when I say that whatever's opposite of what happens to me is normal for most people.
