Reading through this thread the focus seems to be on medical records and attorneys. While that is important the priority right now is obtaining the best medical care possible for your daughter.

My advise is do not let anyone at that hospital even think you might be looking into legal action! Go ahead and document and try to get medical records but be sly about it. Maybe ask for a copy of medical records if she is transferred but again, act as if it's for medical not legal.

Make friends with the nurses. The nurses will not only be important in caring for your daughter they may also be the best source for advising you about doctors. Make friends with the nurses!

Do what you can to get other medical opinions. Another reason not to tip your hand about contacting an attorney, other doctors which may be able to help will shy away if they get word about legal action.

First priority, the best medical care for your daughter. Also good idea for a family member to be at the hospital at all times. The night shift is a good time to pick up information. Also monitor whatever they are doing for your daughter but again in a polite manner

You catch more flys with honey. My career was hosp. admin I know first hand what happens once legal action is a concern. For now be as nice as possible and do whatever you can to get the best care possible for your daughter
