We seldom have breakfast at home, esp. when my boy was still a baby and he only had milk in the morning. What I did with my ex-bun was to buy white bread and peanut butter/ jam etc for her, and told her that those things were for her. I also provided coffee (she was ok most of the time). She never cooked breakfast for us during her 2 years in my house, so she knew that I was buying extra food just for her breakfast.
