Husband: I think he’s done a poo.
Me: Let’s change him.
Husband: I’m not sure though… It’s not so long since I changed him.
Me: Have you checked?
Husband: No. [Pause] You smell him.
Me: I’m eating my porridge.
Husband: You’re so picky…
[Five minutes later, it was clear to us all that a poo had indeed "been done".]
