DD is 16 weeks old today, exclusively breast-fed, gaining weight very well. Only has a poo about every second day, v little for a breast fed baby, A fairly normal breast-fed poo. I breast-fed my other dd and she was the usual, poo-ed 2 or 3 times a day. I hadn't thought this was causing any problems, bu lately I feel she's in discomfort. I suppose the discomfort could be teeth or anything. I'm reluctant to do anything, the books say do nothing but if she's in pain?? Sleep also v poor, and I feel that sometimes tummy cramps are waking her. Any advice?
