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.
Once kittens reach 4 weeks of age, their mother usually begins to wean them off milk and onto solid foods. Because the weaning process can take up to six weeks, purchase a small amount of kitten milk replacement formula and mix it into your kitten's food during his first two weeks with you.
If the kitten paws and scratches at you when feeding, wrap the kitten in a towel. Not only will the towel keep the kitten warm, it will prevent the baby kitten from scratching you as you feed it. Newborn kittens will eat every 1 to 2 hours for the first three weeks.
