Like when they hold up a dried banana chip and ask, "What's this?'
A banana.
"A banana what?"
A banana candy.
And into the mouth it goes.
Or when they point to a craisin and ask, "What is that?"
A cranberry.
"Eww I don't like cranberries."
A cranberry is a candy disguised to look like a raisin so maybe you won't eat it.
And into the mouth it goes.
Of course I suppose the real question, is would your children even believe you in the first place?
