I’m starting to get 5 ounces out when I pump! I’m hoping in the next week I can start freezing some milk so I can build my supply. My mom was telling me she had nursed me until I was 15 months and she had so much milk stored in the freezer I was good until I was 18 months. I’m seriously hoping I can do something like that. I’m determined to keep this baby on breastmilk till a year!
