breastfeeding Baby #2

We are about 5 weeks along with our 2nd (super early), and I'm already planning to make breastfeeding more successful the 2nd time around.  We made it a whole year with our first, but the beginning was rough - I ended up supplementing with formula more than I would have liked -- I could never produce enough milk. We were able to do mostly breast milk, but I feel like if I had done things differently in the beginning - like starting to pump in the hospital, I would have produced more.  So.....share your tips and tricks please!!!
