Here is what a four-year-old thinks; “if I say I am hungry, dad will say it is o.k. for me to have some gummy vitamins.”  The conversation goes like this.

“I want vitamins.”

“But you already had your vitamins for today.”

With a moderate whine, “But dad, I’m hungry!”

“I understand.  How about an apple.”

“No, I want vitamins.  I’m hungry.”
