My daughter loves food but she is a grazer when it comes to eating. She eats little bits all day long. Every other sentence coming out of her mouth is: "I'm hungry." Even when she can't be because she just finished a meal. She'll proclaim she's hungry anyway.
The other day I was trying to get her to empty her plate in one go. The incentive of becoming a member of the Clean Plate Club did not do much. She kept saying she was all done. So I resorted to a new technique: old fashioned bribery.
"Lola, would you like some ice cream?"
"Yes! Ice cream. I love ice cream."
"You must finish your meal first. No clean plate, no ice cream."
Worked like a charm.
