Well, we finished the S26 AR, and decided it wasn't making much of a difference, and was also making him constipated, so went back to regular S26. That fixed the constipation, but the huge vomits came back with a vengance, so now we are trialling Karicare AR. It seems to be working brilliantly with only a little bit of vomiting still, but today again after 3 days of this formula he is constipated again!! Poor little man *TMI* had the hardest, driest little nugget in his nappy this morning! Just wondering if others have had this problem with thickened formulas, and if so, was it ongoing or did it fix itself? I will try getting some water into him today and maybe some water with brown sugar if that doesn't work. Any other suggestions? I don't really want to give him juice yet if I can help it.
