Here's how Duane answers the question, "How many more bites?"
Somewhere along the line my wife or I made the mistake of telling our three year old, "Just 2 more bites." Now, with every single meal, all we ever hear is, "You tell me how more bites, Daddy? 3 or 4 or 5? And then I'll be done." When there's still plenty of food left on the plate you can't really say "Thirty" or something like that because she can't really comprehend what that means like she can comprehend a 5 or a 6.
Today at lunch, over raisins, I tried a new trick. I put one raisin down, and then a pile of 2, a pile of 3, 4… and so on, up to 6. Katherine watched me do it as counted them out. Then I pointed to the piles and said "I want you to eat 1 2 3 4 5 6 raisins and then you'll be done." Thrilled at this idea, she gobbled them down, stopping in the middle to announce "I'm on 4, Daddy. Then I'll just have 5 and 6 and I'll be all done." So instead of 6 raisins I got 21 into her.
Over dinner it worked again. Having cut up a hamburger into pieces and gotten the same "How many bites?" question I made up piles of 1, 2, 3 and 4 and told her she had to eat 4 bites. Presto, 10 pieces of hamburger down the hatch.
