It's Raisin BRAIN!!

So feeding Harley breakfast has been fun! He wants Raisin Brain...I said you mean Raisin BRAN and he said "NO!! I want raisin B-R-A-N...brrraaaiiinn!"....I guess the english language is pretty confusing and he's learning how to sound things out now and figures it's an A so it must be the long A sound....
