I think you are thinking of the phrase  the other way around , which does essentially mean the opposite, but in a specific way. The specific nature of the other way around is that it means that doing what you say in the opposite direction is correct, not necessarily the exact opposite.
You can offer your kitten either dry food, canned food, or both. Be sure to choose food which is designed for kittens. They require a diet which is especially rich in protein, calcium, and other nutrients. Cat food that is for adults is not sufficient.
At this age, the kittens can start receiving kitten mush. A high quality dry kitten food can be placed in the blender with liquid kitten milk replacer and hot water. This should be blenderized until the consistency of human infant cereal. The kittens should receive 3-4 meals a day of this to start.
