Thanks - he is 5 months old on Thursday and i was told it was ok to dilute prune juice with water, but he didn't like it - just screwed up his face and pushed it away. I also tried cooled boiled water and he doesn't like to drink it either.... I have been using Brauers Stomach Calm which is good and clears it up for that day but then it comes back again.... If it continues I might just take him to the doctor.
