Totally agree with all the posts up above, although just for the record, it was the first doctor who said that Truly had the flu --- so it's understandable that the family believed it. This show had me in tears too, and I was so worried for that sweet little girl, ESPECIALLY when first the kidney medication didn't work and then the dialysis didn't work. OMG! I'm a nurse, and I've never seen anyone recover after that.
I know that the Browns probably "should have" picked up on Truly's symptoms, but I also kept thinking about my own children, and how when they were small, there were so many times that I probably didn't pay close enough attention to what MIGHT have developed into a major problem, but thank God, didn't. Wow! This was a really emotional episode for me!
