When my kids were in grammer school, cereal was usually the breakfast of the day. If I felt like it, and got up early enough, I would make scrambled (strangled eggs according to my kids) for everyone. They also had toast with them. One kids was in charge of the four slice toaster and another one the butter.
On Sunday mornings, before heading out to church, I made a big breakfast for all. Eggs of their choice, and bacon done in the oven. There was also home fries along with toast. Of course there was always one that wanted poached eggs. Then you would hear a chorus of poached eggs. It never failed. So I already had the pan of water simmering. I also tried to have juice in the house. Usually tomato. Today, they all still try to have a full breakfast. They never got into the habit of just a cup of coffee and run out the door. It is just a matter of setting the alarm a little bit earier.
