I'm so sorry he isn't feeling well..often the stress of a big change can cause problems. Good job on getting the proper ingredients for the bland diet. Boil the chicken and add cooked rice..I always cook the rice in the boiled chicken water..makes like a broth..give him 1/2 cup at a time.
This is important. The canned pumpkin needs to be 100% canned pumpkin..not pie filling! Add a tsp of this to the bland diet. I hope it helps him quickly! He is so cute..
