My three week old acts as if she's not getting anything from breastfeeding. She seems frustrated and starving increasingly throughout nursing session. I feel forced, and therefore do feed her a bottle (usually previously expressed breast milk but sometimes formula). I suspect there's some nipple confusion or that I messed up by giving her a bottle too soon which I know I shouldn't have and should have waited until breastfeeding was well established. Anyway, what do I do now? I'm exhausted by the constant pumping and these hour long sessions that end in me giving her a 2 or 3 ounces bottle anyway. I figure I'd save time by just pumping and giving her that but I really want breastfeeding to work. By the way when I do pump, about every three hours, I'll get 2-3 ounces if there hasn't been nursing in that time frame. When I pump after nursing, I'll get about an ounce. How do I get my baby full from breastfeeding? Is there any hope?
