Ok it's not colic, a colicy baby just never sleeps. Your baby just has her days and nights mixed up. If her growth/weight gain is normal and she's eating like normal does she ever seem to not be satisified? She very well could just still be hungry. Have you started her on cereal at night yet? If you nurse her don't forget they break that down so much faster than formula or cereal. If she's sleeping all day she's not very tired at night. Try to simulate her more in the day time to keep her up more (I know easier said than done) I would introduce her to cereal. Also have you tried using lavender items? They are very calming. I know What it's like to have babies that don't sleep mine all did it to me. My sister has a lil one who doesn't like to sleep now she uses these and he sleeps like 5 hours at night at a shot
