From experience you want to get them used to noise rather then keeping things quiet. With the first child, I made the mistake of hanging out of the window at 10PM trying to get the attention of the pizza guy so he didn't ring the door bell so we got to eat in peace. By the third child, you could set a firework off in the living room and she'd stay in bed. Be noisy! Be free!
