I don't know if this is just me or if it's something that works, but I'm sure I read (and it worked for me), that pressing down hard with the heel of your hand on the boob you're not feeding from, during let down, 'trains' your breast not to let down/leak. That sounds crazy. It did work for me though I had a good supply (and overactive letdown) but never had to use pads past about 3-4 weeks.
