Breakfast can use the same foods
Breakfast does not need a separate menu. A food they eat at dinner can show up in the morning.
One set of foods for the day
Oats, fruit, egg, or bread are enough when those foods fit their diet and allergies. Keep the new food for the meal where you have time to sit.
A child who eats rice at dinner can eat rice in the morning. You do not owe breakfast a different ingredient list.
Where the new food waits
Morning is often rushed. Serve the familiar food, and save the new food for the meal when someone can sit.
If wheat is an allergy, oats and bread stay off breakfast. Rice, fruit, potato, egg, or yogurt can stand in when those fit.
A breakfast that is enough
Fruit and a food they already accept is a complete breakfast. A second course is optional.
Sit for a few minutes if you can. Standing over them with a spoon makes a simple meal feel like a task.
A sentence you can say
“Same banana as last night.”
