GOOD FIT
During pumping, your nipple
moves freely in the breast
flange tunnel. You see space
around the nipple. Not much
areola is drawn into the tunnel
with the nipple.
FLANGE TOO SMALL
During pumping, some or all
of your nipple rubs against
the sides of the breast flange
tunnel.
FLANGE TOO LARGE
During pumping, more areola
is drawn into the breast flange
with your nipple. Your areola
may rub against the side of the
breast flange tunnel.
