Not making enough milk :(

Need advice, ladies! Thanks in advance...

My baby girl is 9 days old, and I started to pump/breastfeed on day 3. I was going to just formula feed her, but I really wanted to just try giving her breast milk as it's so healthy for her. I think because I started late I can't make enough milk :(

I have tried pumping more often... any tricks I should try? I'm going to a lactation class at my hospital on Wednesday. Right now she's eating 50/50 breast milk and formula. I wish I could get these utters to work so she could be 100% breast milk! 😂 dairy farm is failing... help!

Oh, of course I'm going to post a pic of my little banana.

Thanks!!❤️
