Is it normal to not remember anything before age 7?

Between all of my tags, my memory is slop, lol! I did not know that PTSD could affect memory as well, though, so thank you to everyone above

This is very common for us PTSD folks

Some people definitely can remember things from when they were quite young, but I dont think it's very common. I remember things here and there from when I was like 4 or 5. Mostly just significant events like when we moved across the state or when I had to get stitches in the back of my head, but I really have to sit and think. I have a lot more memories from 6-10, but from 11-17, I'm missing quite a bit. That's PTSD for ya! That, or I just have a terrible memory 🤔
