The scene: In bed, lights off, just about to fall asleep.
Husband: Please be careful how you sleep tonight.
Husband: Last night, Ellie kept licking my face, so I put her between us to sleep. You kept moving around, and then you rolled over right on top of her! You could have smothered her.
Me: Oh dear. (Hiding my grin under the sheet.)
Husband: Just don't do it again. (Totally serious. Mostly.)
