I don’t have cereal often, but when I did, its making sure the cereal is flat and even (as opposed to being piled up in the middle of the bowl like a mountain made of cereal), then pour the milk so that the milk, almosts reach the line where the height of the cereal was, and at the same time some cereal starts to float, and most of the cereal is submerged. I wait for my cereal to get just slightly soggy, then start eating.

(I don’t observe other people eating cereal btw, and IDC about what the cereal eating “norms” there are 🤷‍♂️)
