We have a 6 day old baby who was 9lbs when born - We are formula feeding and finding it hard! For example, tonight she had 4oz at 1am and was really sick - by 220am she was absolutely hysterical and nothing would console her - changing, playing, cuddling, music etc and all she seemed to want is a bottle so given her another 2oz over the last hour - she's still not satisfied but we can't just keep giving her milk! Any ideas as to what we're doing wrong? Some nights/days have been fine and others have been endless crying but can't keep giving her bottle after bottle.
