Our experience with the Bubbles - Mango - Peaches introductions was that showing more consistent attention to the cat who is having the worst time adjusting to the new situation helps them overcome their discomfort. Besides the other two are having fun so they won't feel cheated. It still takes time to work it all out but it will.

Mango started out as a super affectionate kitten and has only gotten more affectionate as an adult. They don't grow out of it, they just get more proficient at it!

Mango curls up on the pillow beside me with the top of his head against my cheek - and purrs himself to sleep. The first time he did that he was only four months old. Now he's two and a half.
