I think we’re on opposite ends of the spectrum. I don’t have any large gaps, except one year of my childhood, when I was seriously depressed after a traumatic event. I remember WAY back. There are probably as many of us who remember early childhood (before 2 years) as there are who don’t remember much before adulthood.
IIRC, the vast majority of people don’t remember much before about 2 or 3 years old. Of those memories, the strongest ones are often traumatic or emotionally charged or are special events like birthdays. Interestingly, this is the age where language skills are booming, and it is possible that we don’t remember preverbal stuff well once we become verbal. IIRC, again (no irony intended), most early memories are bits and flashes, sometimes sorted in the wrong order, or combined from more than one memory, or generated by stories from others. Daily stuff usually goes away, filed, but not accessible because you don’t travel that path often. And if you do spend a lot of time on a particular memory, it tends to be overwritten by the remembering - much like how a birth story is modified over time, highlighting some parts, forgetting others. I’ve been entertained by the differences in how I’d write my son’s birth stories NOW, vs. how they were written immediately after the events.
It is probably not the norm to not remember anything at all before your teen years, but not unusual to not remember things unless prompted. Some of my friends don’t remember highschool or younger unless someone prompts them. They remember what they learned, just not daily events, classes, etc. They remember their friends, but not what they did with those friends. I have a different issue - if I can’t remember it on my own, I often can’t remember it when prompted, either. I’ve already maxed out my prompt capacity with my own processes.
Capacity for long memories does seem to have a genetic component - long memories certainly run in our family. I can remember nursing, even though I was weaned by about 6 months old. :eek: I remember a variety of physical or visceral experiences, from how annoying it was to wear diapers when I was crawling, to the physical experience of eating spaghetti while sitting in my highchair, to being carried in a laundry basket (on top of the clean clothes) by my mom - the feel of alternating early morning sun and cool shade on my skin, the smell of clean laundry, and the rhythmic thump as the basket shifted and dropped against her leg or hip as she walked. I also remember intense emotional reactions, like the incredible overwhelming need to repeat a behavior that made my mom laugh - it was a flooding sensation, powerful, addictive, intense … knowing that something I did generated her (to me) beautiful laughter was both powerful and maddening - I was as driven to repeat grabbing her nose (I was about 9 months old) as I am now driven to repeat something that makes my son laugh. Totally hard wired reaction, and impossible to ignore. I can clearly remember the details of that particular event, from the precarious perch on her lap (she was holding me upright, but I was doing the standing, if that makes sense), and as I grabbed for her nose, she’d turn her head to her right (my left) to keep it away from me - and laugh. I still can feel the need to make her laugh again.
I remember a great deal from 2 and older - school (pre-K, K, and pretty reasonable stream of daily and special events from then on), home, family, environment, friends… I also remember huge amounts of data, research I’ve read years ago, conversations I had years ago, etc. Still, I’m aware that memory isn’t a snapshot - it can shift, warp, be overwritten, be modified, etc. So, while I have memories, that I THINK are real, I can’t rely on them to be 100% accurate. Most of the really early ones have since been corroborated by others, but even that corroboration can be wrong, or can mix with the wrong memory, etc. So, I have memory, but is isn’t necessarily accurate. You, at least won’t have to wonder if your childhood memory is accurate…
BTW, almost all of my early memories are physical memories or have a strong physical or physical-emotional component. I’m a kinesthetic learner, so physical cues are a major part of my memory process. I’m not sure if it makes it easier to remember preverbal stuff, overall, but certainly cueing in to how you store information helps with recall. Here’s more on the learning modalities and memory.

I suspect that a lot of people have large gaps, though. I’ve seldom met anyone outside my family who has as long a memory, let alone longer.
