Great advice given here already.
Another vote for using lansinoh from the first day.
What earnest said about the second night. Yowsers.
Definitely look up how to read your baby's cues. By default you often think they're crying from hunger when it could be wind, discomfort or tiredness. I found that the baby whisperer book had a few good tips about this.
BF babies still do require winding.
The document showing latch (linked by leedy) looked very good.
Agree with what noblegiraffe said, as it's very important to prevent dehydration. It can bring on jaundice, which isn't an uncommon thing (but may require phototherapy at hospital).
Be prepared to hear very conflicting advice. Seek clarification. Seek help with latch if you have difficulty or pain. Ask multiple people as sometimes it will just "click" with a different person telling/showing you.
When asked if latch is ok, you probably won't really know if how it feels is the way it SHOULD feel. If I were to describe the feeling of good comfortable BFing I'd say that it's a bit like having stitches after a local anaesthetic... you feel tugging but no pain.
Speaking of pain, I think most people experience a degree of pain/discomfort in the early days due to friction but it shouldn't be murderous pain.
It may take a couple of (a few) weeks before you realise that BFing isn't just another thing to be endured.
Congrats, good luck and hope all goes well!
