Hello, My Name Is Haley Hodge I Have A 6

Hello, my name is Haley Hodge I have a 6 year old disabled daughter which can not do anything. Meaning can't talk, walk, bottle fed, can't use her hands, doesn't know how to cooperate, etc. here recently, about every other week now she has been throwing up brown vomit. I'm extremely concerned and was wondering what your opinion would be on what this could be.
