do you remember your childhood?

alot of people remember their childhood as their own and how they felt in a certain age but I don't remember anything. I realized I don't remember my childhood when my sisters were talking about smth that happened when we were kids and I didn't know what they were talking about. I don't think i was too young to remember cuz my sisters are younger than me so what's wrong with me? why can't I remember and is there anyone else who doesn't remember?
