any mamas who are breastfeeding.... I have been breastfeeding for almost 7 months now, but recently when my daughter nurses on the right side it doesn't feel like she has emptied it much (I know they are never fully empty) it just still feels kind of full... I've pumped that side and also left it thinking it would adjust itself... any ideas mamas????
