I Said No

For being the conventional mother that I think I am, I must do a lot of things unconventionally for THREE sons to wake up and say this:
(And these are the first words out of their mouths, mind you)
"Mom, can we have Oreos for breakfast?"
"No."
"OH-uh!" Greyson groans in unbelief and disappointment.
Next up is Tristan's running commentary on what Sawyer is dragging out from the pantry:
"What are you doing?" I ask Sawyer.
"Those are Coconut, we're having them with the oatmeal," enlightens Tristan.
"Can we have these cookies, Mom?" Sawyer asks hopefully.

Can you guess what the conventional answer was?
