One size doesn't fit all when it comes to breast shields, the plastic suction cups that fit over your nipples while pumping breast milk. Shields that fit correctly make pumping more comfortable and efficient. If you've been using the standard-sized shields that came with your Medela pump and your nipples aren't enclosed by the shields or they get irritated while pumping, you may need bigger breast shields. Medela makes two sizes — large and extra-large. Extra-large nipples are rare. To determine whether you have them, hold a half-dollar over your erect nipple (the way it looks when your baby is nursing). If your erect nipple is the same size as the half-dollar, order the extra-large shields. If your nipples are closer to the size of a quarter, consider Medela's large breast shields .
