Christmas If dd is still bf, it might be worth dropping wheat and dairy from your diet for, say, two days just to see if it makes a difference to her. There are no bowel symptoms in the two food intolerant babies I know about. They just behave as if they have the worst teething problems ever, and don't stop until the offending food is removed. I'm not quite sure how it's dealt with in formula feeding as my ds and his friend were both ebf.
With ds and myself, when we removed wheat and dairy, quite by accident, the symptoms vanished in both of exactly at the same time, 14 hours later.
Ds doesn't get on with added vitamins in food, so I think he might have been in real trouble if I'd given him formula. I've never actually tried it to find out. I don't think that can be very common though.
