So I’ll be a FTM in July and was wondering about how to have extra supply in order to store up for later. I’ll begin work six weeks after she is born and I want to make sure I have a good sized stash. How often should I pump? Do I pump at night? If she doesn’t nurse for 15/20 minutes on each side, do I pump out the rest to avoid my breast swelling up? Any advice is welcome!
