My three week old baby girl has always had good sleeping habits...usually gets up about two or three times during the night. Last night, however, she went to bed a little before 11. She got a little fussy around​ 1:00, but by the time I came back with a bottle of breast milk, she was already back to sleep. Then, didn't get up again until around 4. I'm not sure if I should be nervous about how much sleep she's getting and not eating during the night, or be super excited about it.
