paranoia

My toddler likes to run around naked.

She was talking about poop all day, asking if she'd pooped in her pull-up (when she was naked).

I didn't think anything of it at the time.

But now, hours later,

I am sitting in the living room. 

I smell poop.

I have looked everywhere.

I can't find it.

Did she poop in the living room?

Or is my mind playing tricks on me?
