The way I did it was to pump for him until he got used to the bottle (I would do one bottle a day, then two, etc.). Then start mixing formula in with the expressed milk progressively until you know the little one won't notice when you stop using your own milk (the formula tastes way different so you do have to be kind of sneaky about it). Eventually you will be able to stop mixing them, but since yours is over a year you might just start with a sippy cup instead of a bottle, to kill two birds with one stone. When you know the babe won't notice the lack of breast milk, cut it out completely, and be prepared for a week or so of serious pain. But if you cut it down progressively, it isn't so bad as just stopping immediately.
