How far back in your life can आप remember?

How far back in your childhood can आप remember? How old can आप remember being? How far back in our life can your brain take you? What childhood pictures can आप remember taking? How far back in school can आप remember? For example: I remember my years in preschool. I remember being babysat द्वारा my grandmother (granny). I was told that my sisters also babysat me but I can't remember that. I was told my family and I went into the st. louis arch but I don't remember that. There are a couple of pictures I remember taking but I don't remember what age. Mom told me I was 2 and 3 when I took those. How can anybody remember themselves being that young? I sure remember taking those pictures and when I was told how old I was, I was pretty shocked. I was that young? And I still remember taking those today at age 24? I guess some people can remember being that young. Even when they don't realize it. If y'all wanna see what pictures I'm talking about, just got to my प्रोफ़ाइल and you'll see them. I would post them here with this सवाल but I don't want anybody talking about me. Saying "why आप posting a picture of yourself as a little girl? We don't wanna see you" and stuff like that. So anyway that's how far back I can remember. So what about y'all? And आप can post a picture of yourself as a kid if आप want to. I don't mind at all
