When I stopped the night feeds for my boys (twins) at first I would get up and cuddle them back to sleep (I would all asleep too in the arm chair in their room) then after about a monthDG would get up instead and pat and give them dummy. Gee can't remember at what age this was but it was just before 12 months. Then over winter when they had colds I did give them a night breastfeed again when they needed it but once they were well again they didn't ask for it.
