I'm an exclusively pumping mum.. and I am trying to wean my supply.. how do I proceed to do so?

Start by reducing the duration of each pump session. For example, if you need 20min to clear your boobs, pump for 10min instead. Do this for 3-5 days to condition your body to produce less milk. Then extend the time in between pumps. So if you've been pumping 3hrly, change it to 4hrly. Do it for 3-5 days before extending further and then finally dropping pump sessions. You can do it faster if you want and if your body is able to adjust accordingly. This method is proposed to reduce the discomfort and potentially blocked ducts.
