Here's how to cure hiccups when your kids get them. They say, "Darn! I've got the hiccups." You know they do 'cause you've already heard about a half dozen or so. But you disagree and say, "No, you don't."
"I do! I do!"
"Well, then let me hear one."
They will sit there and concentrate so hard and try their best to hiccup, but they won't be able to. My dad amazed me with this trick, and it's worked pretty good on mine, up until around the age of ten. That's when they're smarter than you, you know.
