Falling down the stairs when I was 2, probably.
I have recollections of doing a full cartwheel, smacking my head off the stair and splitting my head and nose open. Fun times.

I can't remember to be honest.

I think they were,
they took me to a bowling alley a couple of years later where I proceeded to trip on a step and split my head open again. Coincidence????

Hard to say. I will look into the case file.

Ooh, I remember sledging down the stairs on the toybox lid
and on arriving at the bottom at considerable speed being catapulted into the wall opposite with some force.

Good times.

I did almost exactly the same. Ended up winded for the first time in my life and was convinced I was dying. My mother laughed and stepped over me.

But there are no mental health issues as a result. Probably.
