Not really. My Ped said it didn't sound like a diarrhea. He said diarrhea should be very very watery. But it is also not normal to have 5 poops in a day for my LO. But as long as he is happy and not sick, we shouldn't be worried about it. If I want to find out if it was b/c of the yam he ate, I can try it again later and see if he poops frequently again. Anyway, after that day when my LO had 5 poops, he had 3 the next day, then 2 the day after. Now he is back to normal.
