I'm glad they found a treatment that will work for Kassie Glo, but don't blame yourself for this, I don't know with Kassie but with Sonya I used to get NO WARNING at all that an ear infection was starting except for the high fever. I had a lot of problems when we were living in NJ with her and her ears , we were about to place tubes in them but we moved to PA and the first winter she only got one infection , that was the last one she ever had. Her bronchitis then started getting really bad and the doctor started giving her the flu shot, it works wonders for her and she has been getting it every year since , same with Rebecca.
Bottom line is they can get VERY sick and it's not because you do not take proper care of them , it just happens. Darn , the day Sonya was put in the hospital with croup I had taken her to the doctor's office and he said it was a "plain" cold and sent us home with no other medication than Robitussin, that same night she was admited in the hospital with croup!
I know it hurts to see them hurt , but sometimes we can't control that. {{{{{{{hugs}}}}}}}}}
