What do you feed your children/teens for breakfast each day?

I attempt on most days, my son eats because he has athletics first period and has to be there early. My daughter only occasionally. I've offered to buy whatever they wanted for breakfast, within reason.

Lots of things....
Blueberry oatmeal
Eggy toast (whole cut in middle of toast and drop an egg into it)
Eggy flowers ( same concept but with bell pepper slices)
Breakfast tacos
Pancakes
Greek yogurt and blueberries
Veggie frittata using leftover veggies from dinner
Biscuits rolled out and stuffed with scrambled eggs, chicken bacon and cheese
Biscuits and gravy

Lately, Cheerios, bacon, cantaloupe, and honey bread. She's 5.

I cook a big breakfast at least 4 days a week. Usually that is some combination of bacon, ham, sausage, oatmeal, biscuits and gravy, blueberry waffles or pancakes, french toast, eggs, omelets, quiche, etc. On the days I have to be to work early, it is the quicker stuff like toast, yogurt, cereal, fruit, etc.

Varies. Today it will be eggs, sausage, and toast.

Other things:
cold cereal
oatmeal
grits
cream of wheat
homemade egg mcmuffins
omelets
french toast

We like a hot breakfast, but I like something fast and easy as well. Big breakfasts are usually reserved for special days.

My 15 yo has a bowl of Cheerios and then gets a chicken or sausage biscuit with fruit at school
My 13 yo and 11 yo's eat cheesy grits
My 4 yo and 2 yo eat pancakes, scrambled eggs, cheesy toast, French toast, etc with yogurt and/or whatever fruit we have

Breakfast is kind of quick and understated around here. Cereal, toaster waffles, cereal bars, fresh fruit, toast or a half a bagel.

my teen boys eat a variety of foods for breakfast such as Uncrustables, muffins, pop-tarts, granola bars, yoghurt, fruit, toast, French toast sticks, pigs in a blanket...... depends on what we have on hand and what they are hungry for that particular morning.
My 6yr old is not much of a breakfast eater, but lately he has been asking for mac & cheese (sometimes I add bacon to it) - thank goodness for Kraft Easy Mac!!
