How do you help baby back to sleep after night feedings?

My baby girl thinks day is night and night is day! All night she wants to play after nursing and all day she's passing out directly after I nurse her! I know I should try to set the stage for sleep but having the lights out makes me fall asleep sitting up. What do you ladies do to help babies back to sleep at night? And up after feeds during the day?
