Are you ok with butt?

Buth is a type of cereal made from cracked wheat. While we were going to bed yesterday night, Tanish all of a sudden asked me, "Daddy, are you ok with butt tomorrow? " I had no context and I asked, "What butt? lol . He then said, "woof, the breakfast butt". It took a few seconds but eventually I got what he was trying to say.
