Unfortunately, big breasted women often feel more challenged when it comes to breastfeeding and pumping, according to international board certified lactation consultant IBCLC Leigh Anne O'Connor. These can be expensive, but there are options to rent, and as you continue, a hand-held pump or personal size electric pump could work just as well. Some small breasted people need larger flanges while some large breasted people need smaller flanges. In the same way that it's helpful to learn what assists large-breasted women when nursing , there are some pretty specific things you can do to help making pumping go a little smoother because like everything in life, it's about finding the right fit, the right procedures and the right equipment.

Spradlin says that the flange size should be 4 mm larger than the nipple.
