As strange as it is, I would watch old family videos and would remember what some of my perspectives or thoughts were during those moments. For example there was a video of my family and my Dad and his brothers (our uncles) were playing with a 3yr old me and my 4yr old sister being goofy with us, and my sister and I were eating carrots. While watching the video I remember I actually didn't like the carrot and I remember why I didn't like it, and that I was only eating it because my sister liked them and everyone else was having fun so I wanted to too, lol. (For most of my childhood I didn't have the self-awareness to think for myself, I always observed my sister or others and tried to like what they liked, do what they could do, be my sister's little clumsy shadow, etc.)
I also have some very vague memories that go back as young as 2yrs old but they continued until older ages so no guarantee of what moments I'm really remembering from. I remember enjoying my thumb while twirling my hair, playing with a baby toy and remembering the feel of the texture of the toy (the plastic type of toy you stack colorful rings on), children books and what their covers felt like as I pulled them off the shelf and sprawled them on the floor, or stuffies and the feel of their fur or eyes or both.
Of another memory, when I was about seven I ended up with a baby brother, and when we had his baby things I would remember what they were like when I used similar items, like a binky suddenly felt nostalgic to me a seven year old, but at the moment of playing with my baby brother's binky I remembered my own binky fun (I don't think it's infant binkies I remembered, but rather when my other siblings and I were 4 and older we goofed around with some of our baby things). Either way, my seven year old thoughts bridged me to younger thoughts, and then those memories stayed from those moments. So yes, I strangely sort of remember what a binky felt like and tasted like. That's a weird thing to reminisce on, but then again I guess I subconsciously took notice of details even at very young ages.
Memories are interesting, but I feel there's a part of me and how my thought processes are that's always been simply me. These days I enjoy the details of jig-saw puzzles, macro photos, and the feel of my pets.
