[Krishna's Mom]

Hi, I've posted before about Kita's tummy troubles. She had a lot of mucous in her poop and started getting blood in it. Her tummy made such loud growly noises you could hear them from across the room. The vet has put her on clindamyacin twice to get rid of bacteria in her tummy (apparently normal intestinal bacteria on a growing binge).
The second time we removed everything from her diet (she was getting a tsp of baby food chicken or a bit of cottage cheese with her meals) so now she only gets Diamond Lamb & Rice Dry with a tsp of Nutro Max Lamb & Rice wet mixed in. She also gets about 1/2 of a Luv a Bones wheat free corn free treat every day. Yes. her diet is wheat free and corn free - has been since she was born. She has been fine for the last two weeks, but I let her chew on a bully stick for about an hour last week and her tummy was upset again the next day so I figured the bully stick caused the upset.
Now she has a terrible growly tummy again this morning but I can't come up with any reason for it. She hasn't had anything but her food.
I'm hoping somebody here has some good advice on what kind of food to buy for a little one with a really sensitive stomach. Any advice would be really appreciated as I seem to be continually stressed out worrying about her all the time. Other than the tummy troubles she is a completely healthy and happy 2.5 pound 7 month old little girl.
