Lucie has been unwell with gastro since Monday night. It was mostly diarrohea after a nights vomiting. We went through stopping formula for 24 hours on 2 occasions and then restarting at half strength and increasing. The second time it appeared to work, with no diarrohea (but she wouldn't take solids and still very fussy on bottle) for 48 hours and then it hit again. Now we are back to half strength but she keeps sucking then stopping and groaning in pain and it's like her tummy is cramping up. Could it now be a lactose intolerance (I have heard it can happen after gastro)? And should I try a lactose free formula for a while? Has anyone else had this? I am going out of my mind! I just want my girl to be better again. She is so tiny anyway and she can't afford to keep losing all this weight!
