Re: desperate need of help!!!
A lot of what you describe sounds like baby is having a problem with oversupply and fast letdowns. You nurse on just one breast at a time, never feel like the breast is drained and soft, and baby is making classic fast letdown noises (gag, gulp, gasp, cough, click) and pulling off the breast. I think you can pretty safely assume that some degree of oversupply is occurring right now. The best thing you can do to start is to adopt reclined nursing positions and see if that helps. If it doesn't, you may need to do some block feeding, but you probably don't want to go the just yet.
Be patient, mama! All the problems you are having will improve in time. As your baby grows, she will become better able to handle rapid milk flow, and your supply should eventually adjust to meet her needs a little more accurately, without so much extra milk being made.
