I am 8 days post partum and I am still only pumping 5 oz a day. I have to exclusively pump until my premie baby gains more weight since she uses all her energy eating. She gets about half formula half breast milk. What can I do for my milk to come in? I pump every 2-3 hours all day and night long for 15-20 min. I don't miss a pumping. Will my milk even start to come in more? I'm getting very discouraged. And tired. When my baby sleeps I want to sleep some and not pump lol.  Anyway, suggestions ? Comments ? Help
