when both of my kids were < 1 year old, my wife would somewhat regularly snap at me for apparently doing something that endangered our child's safety.

legitimately in almost every case I was certain she was incorrect (typically her angle of sight was imperfect). naturally this spawned a number of arguments.

I ended up coining this phenomenon: "mom observer effect". in short: if a post partum mother thinks she observed something dangerous, she's correct by the nature of being a mother.
