I can only remember a few things from age 2-3, things that were extremely scary to me - I followed my grandmother into the bathroom and she took out her teeth. She might as well have taken off her head, it was so unexpected and terrifying. LOL
Another scary memory from that time was putting my face above a bucket in the garage and finding a monster-bird hopping up and down at my face (that is my memory of it, but from my mom's telling, it was the neighbor girl's pet hamster that had escaped and then managed to get stuck in a bucket in our garage - it was returned safely).
Then there is a memory of how scary it was riding on the handlebars of my mom's bicycle when she went to the store, though that is kind of a strange memory because it happened a lot but seems to have left one generalized memory.
Years 4 - 5 have more memories but still mostly scary, falling and scraping my knee, getting barked at, the embarrassment of wetting the bed once, etc.
My sister cut her face at the park and asked if I had a tissue to mop the blood, I did not, and my failure shook me up to the point that I don't think I've ever gone anywhere for the rest of my life without making sure I have a tissue! From hearing details when I was older I know it was a significant cut and my parents took her to get stitches, but my own memory still feels like if only I'd had a tissue my sister would have been okay.
