Hailey is our little trooper on Friday the doctors decided to give low flow oxygen a try. So far she is doing well we just hope she doesn't get tired and need the high flow back. Hailey is 18 1/2 inches long and 6lbs 5 oz. We are beginning to feed her with a bottle but we are far away from her taking every single feeding from the bottle. In order for her to come home she need to eat 2 oz. every 3 hours for 3 straight days for them to even think of letting her come home.
