What kind of formula do you have her on? If it is KMR, then I would replace the container or switch to goat's milk.
Bloody diarrhea can be an indication of intestinal parasites, giardia or coccidia. If you can get a small sample into the vet for parasitic analysis, that might rule out intestinal parasites.
If it were me, I would try to introduce her to a little bit of chicken meat-only baby food. My suggestion to you would be to boil about a cup of long-cooking white rice, let that cool, and then puree it with the baby food in the food processor or blender until it is soupy but not runny. It needs to have a little consistancy. Warm it gently and then offer it to Jade. The chicken and rice is very helpful when it comes to binding up the stool. I normally smear a little puddle of the stuff on a dessert-sized paper plate and then scoop it up on my fingers. I offer it to the babies, but if they don't take to it right away, then I help them out a little by putting just a small bit right into the mouth. They get the idea pretty quickly after that.
Hopefully, with a little diet change, Jade will feel better soon. But I would think about reducing her dependance on the bottle at this age ... the formula might be the culprit.
