Re: How long should she be eating?
Welcome and congrats on yur baby! 9 days past EDD is actually not overdue- I have read that the average gestation time for a first-time mom is exactly 41 weeks, 2 days! So you were really almost exactly on time, using that standard.
As long as your baby continues to have adequate wet and poopy diapers, there is no reason to worry about the relatively short feedings. Babies get better at nursing as time goes on, and by a few months old, many babies can get a full meal in under 10 minutes at the breast.
Again, normal diaper output = nothing to worry about.
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!"
