successful breastfeeding

Anonymous
Any of you ladies have useful tips on how to breastfeed successfully?  I'm pregnant with my third and always had a hard time producing enough, which would stress me out and I would quit after a couple of weeks. My boys would latch on, but when I pumped I didn't get much.  This time around I'm thinking of antenatal expression beginning at 37 weeks just so I can get it going early.
