I have a friend who is a lactation consultant and she suggested commencing expressing / breast stimulation from about 36 weeks to assist with milk production with PCOS. It is still a debatable topic as to whether it has any impact or not on breast milk production but having taking this long to (hopefully) get an established supply it can't hurt. I didn't do it as I am not a *confirmed* PCOS sufferer - just a few of the symptoms rather than all of them. You can store the expressed colostrum and give it to bubs too.
