I wouldn't give up on the small breast, because it always pays to have a backup. What if baby bites the larger side and suddenly you don't want to nurse on it? In that situation, the small side could come in handy, provided baby will still take it. I would actually start offering the small side at the beginning of every feeding, when baby is more hungry and less likely to fool around and bite. Not only would you be less likely to be bit- hypothetically, anyway- but you might also even put the size difference between the two sides.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
