i really need advice/encouragement, i feel like giving up!

dpraseutsinh

what am i doing wrong!? no matter what position i do, i hear her gulp and swallow and i know i make at least 2 oz in one breast and yet when i offer her a bottle of breastmilk (to see if she is satisfied), she'll down the whole 2oz bottle! is it a latching problem? positioning? also, how do i know she's drained the breast? 

i want to give her the best and i'm wanting to make this work and make us both happy!
