Nighttime Feeding Advice

Kristin
My baby girl just turned a month old. For the last few days, she has had the following schedule: eats 3 oz at 9:45pm, sleeps until she eats 4 oz at 11:45pm, and sleeps until she eats 4 oz 4:00am. Then, she is normally hungry again at 5/5:30am and will not go back to bed until 6:30am. So, she's up from 4-6:30am almost consistently. How can I cut down this time? Should I feed her more at 4am, so she isn't ready to eat again about an hour later? Any advice is appreciated!!! :)
