I have no idea, unless the food is starting to go bad. How old is he now? The reason I ask is that teething can loosen stools. Loose stools can also be because of getting too warm when playing, but the probiotics should help with that. There may be some reason that food is passing through the large intestine too fast, the pumpkin helps with that. That can also be a result of getting overheated. Sorry, just thinking out loud, as it were.
