Help! One side not producing well!

[Nerissa]

My right side produces more than my left. It has with all three of my kids. I really notice the difference when pumping at work.

DD will feed from the left side but now that she is getting a little older she gets fussy on the left side and hungry an hour or so later.

My breasts are almost a cup size different and it is really obvious when I am BFing.
