Stop gradually. You could start by having every other feeding be a bottle and if there's too much pressure pump or hand express just a little to releave it. Or you could stop nursing all together and just pump enough so you are comfortable and gradually pump less and less.
use a breats bump when u stop so you will still get the milk out
Bump... Experiences please!
Just slowly cut down each week on how many times you breast feed so your milk supply starts to produce less and less. Best way i can suggest
