My case is quite similar with tamamafamily. Sucess at the begining, but when baby grow up to 1 month,my nippel feel very painful and breed for 2 times while breastfeeding. I was so frustrated and considering of giving up. My husband told me to make decision whenever i feel comfort. Baby have to drink 奶粉 one day. How i feel is as important as baby's health. So share your feeling with your husband, family's suport helps you a lot. Let other family member to 餵奶 and share the housework.
Don't worry Be a happy ma!
