Anyway... more seriously now =P
Not only have I never eaten any of those things for breakfast, I've also never eaten them at any point at all, aside from one smoothie long ago as a teen that I didn't like (probably due to whatever flavor it was, but I never tried it again anyway). =P
I know cereal is a normal breakfast food in certain other countries, but here it is not. Which doesn't mean it doesn't exist here. It's just not normal breakfast food most people here would eat.
A traditional Dutch breakfast is usually some kind of bread with some kind of topping or
beschuit or
ontbijtkoek. The latter I stopped eating long ago as eating more than 2 slices would send me to the toilet as they are often laxative in my experience =P
The idea of eating some kind of food involving milk for breakfast makes my stomach turn already =\
But obviously it's a matter of what you're used to as well =P
