PART1: My sister switched my baby powder with flour as a joke during a family visit. Thirty seconds after I used it, my six-month-old baby stopped breathing. I rushed her to the hospital

I threw it away anyway.
Trauma is not logical. It is a smell trapped in plastic. A sound hidden inside a cap. A patch of sunlight on a changing pad that your body starts treating like a crime scene.
For a while, I lived by lists.
Check the windows. Check the locks. Check the labels. Check Lily’s breathing. Check the camera. Check again.
Then one night, three months after the hospital, Lily laughed.
Not a weak sound. Not a tired one.
A full bubbling laugh because I had dropped a clean sock on my own head while folding laundry.
I froze with the sock in my hand.
Then I laughed too.
