Hi Kim,
I think you are doing great. My supply didn't come in as fast as I wanted, but it did finally. Just keep up the pumping! Over 2 ozs in 2 days is great! Not to mention once you have a baby at your breast your supply will build up even more. To be honest, I didn't think that would work, but it did I am happy to say!
Just remember to try and stay as relaxed as you can while pumping.
