G.G.
My son (14-mos old) had diarrhea a few weeks ago for a full 7-days. No other symptoms, not dehydrated. I put him on a bland diet, eliminated milk. I told myself if he wasn't better in a week we were going to the Dr. Day 8 he was back to normal! I spent a few days getting him back to his regular eating habits, but he is just fine.
Good luck!
