Hi J.- I just went through this with my daughter. She is almost 9months. She had diarrhea for 4 days, vomited one day, and was just feeling sick for the week. I asked the doc if I could give anything else and they said Pedialite and formula was the way to go. Also Mylycon drops for the gas. I tried to feed her bottles but she wouldn't drink much. I gave her the pedialite in between bottles and she sucked on the pedialite freezie pops too. As soon as she was acting somewhat hungry again, I added in the bananas but she would only take a couple of spoonfuls. Next I added applesauce. She slowly started to get better, but we avoided dehydration with the pedialite.
Hang in there- the poopy diapers will pass!
