We have CVS and Walgreen's in Florida. If anyone goes to a walk-in clinic or doctor's office in Florida, they do check identification of the person coming into the clinic or office and take a copy of the adult's drivers license.
I have personally experienced having my photo taken when I went to a new doctor in Florida.
If the adult bringing in a child claiming they have Turners Syndrome, they will do a thorough examine of the child and ask a lot more questions and looking for some background info regarding the child's primary doctor. In some cases, the walk-in clinic may even attempt to contact the primary doctor in order to check on types of medication originally prescribed for the child.
If a parent wants to claim their child(ren) on their tax return, the child(ren) must have a social security number.
IMO, I am sure that all the doctors, hospitals and walk-in clinics within areas of suspect have been notified of Haleigh's disappearance as well as Haleigh's Turners Syndrome and to be on alert should a child come into any facility needing medical care and medication for Turners Syndrome.
IMO, should a medical professional say to Haleigh: "Mommy says your not feeling well today", Haleigh is very capable of saying: "That is not my Mommy, that is my ....." Haleigh loves her daddy, her mommy and even Misty so she knows enough to correct the doctor.
