I've never really been 'normal', when I was a baby I hated my dad. Every time he held me I screamed my head off, but as soon as mum took me I was quiet again. By the time I reached 1 I was rolling myself around the room, used to get my brother in trouble for it too, until they found out I was doing it myself all along. I skipped sippy cups and went straight to drinking out of a regular cup (tho sometimes with handles), I was a picky eater (still am, sort of) and I would climb on window sills despite falling and hitting my face multiple times.
After that I learned how to walk, which is pretty normal. not much to know after that till about the age of 10-ish when I first learned of swear words (I was raised in a religious home), I still to this day don't use them but it came as quite a shock realising that such words existed and were so frowned upon by my family and the church I was raised to believe in
