DS would nurse a lot initially because he would fall asleep at the breast before he was full. He's much more efficient now and only falls asleep when he's actually tired and rarely wakes up ten minutes later because he's hungry. We were lucky in that he typically gives us a couple of 4 hour sleeping sessions at night, and has been doing that since we brought him home.
Check out your local Le Leche League for additional support too! Sometimes it's just nice to talk to other nursing moms in person, even if you don't have any questions.
