I've ended up saying things like, "Oh! I want the Urchin to enjoy exploring so I just try to put up anything that I don't want her to touch. It's easier than following her around and telling her what NOT to touch."
Then laugh and change the subject.
We have some friends who use spankings a. lot. and they just drop it into conversation with their son, like, "Oh is your baby doll gettin' into trouble? You'd better give that baby a spanking!"
When they tried to include the Urchin in that type of "game" I had to finally speak up and say, "She doesn't know what spankings are."
But it was pretty weird.
