My left breast has been producing markedly less milk than my right breast. It produces about half the amount. How can I increase the supply so that my left catches up? Should I pump for five minutes on that side after each session? Thanks in advance for any advice you can provide. By the way, I don't know if this is relevant, but I seem to have a pretty forceful letdown in my left breast. It literally shoots out. But it is definitely softer and less heavy than the right.
