My tummy has a headache

"Mom I can't eat that 'cuz what if it gives my tummy a headache like I had last time?"

(I was offering him the rest of a Gerber fruit leather that I had tried to give Cloee to see if she would/could eat it and this was his reply. Apparently the fruit leather didn't look so appealing. He did in fact have a really terrible tummy ache yesterday.)
