Hello Ren,
I just want to let you know I think you are doing a great job persisting through all these dramas! You are def encouraging others to keep going. I wish I had tried harder, next time I will. I seem to have had some similar problems as you in the early days and I kept trying to pump and feed but ended up exclusively pumping (still going at 6 months) I did call an LC but she was busy at the time and didn't call back so it put me off. It sounds like you really have a FANTASTIC one! Hang on to her.
You are doing such a great job for your little Ava. Well Done!!!
