I think Riley has an upset tummy. He was fine this morning, but around 8, he started acting weird. I was in the kitchen making food and I decided to give him ONE cheerio. He didn't even want it. I took it with me, in case he wanted it later. He tried to eat it and would spit it out and pick it up again. I can't find it so I guess he ate it. For the past 2 hours his tummy has been making noises. He hasnt eaten anything bad lately. I don't know whats wrong. His stool is normal. What will help his upset tummy?
