How far back can you remember to your childhood?

Specifically, as in having memories from being younger than 3 years old and even further

I orient myself's own timeline upon some early-childhood memories, but some people have questioned it as false memory... which, understandable

But I can draw the layout of every house I've lived in, who's room was who's, where furniture was, certain events (like having gum melt in my diaper, crying in my crib about not trick-or-treating, seeing my first "flying-leaf" insect) and a lot of other random tidbits

A lot of it I've been able to confirm as true, which is what has always intrigued me. How far back is average? I think the furthest I can grasp is around 2 years old or maybe a little less

Maybe some of it has to do with trauma-ish things or something? But I can literally remember the potpourri on my mom's dresser when she was holding me, who was at my 3rd birthday... and just, kinda far back

What's everyone else's memory like here? I feel like my early pre-teens was kinda a blur, but my early childhood seems more vibrant sometimes. I dunno, I was just curious
