i just started breastfeeding DD again after exclusively pumping for 4 weeks and this is how shes eating, 20 mins on one side then shes done. i was pumping about 35 oz a day, so i think my milk is just coming out really fast. any tips on how to get her to do both breasts in one feeding? i've thought about switching sides after 10 mins but my breast doesn't let down till 20 mins.
