That is what I've been thinking did happen. But I do think that that because Anna was in the Bahamas hospital for the birth, and then back again 31 Oct for pneumonia that perhaps the Bahamas hospital may have been lenient about her addiction.
They were more cautious in FL. In People mag, Bonnie Stern gives an interview about how very sick ANS was that last week, but "Anna wouldn't let them take her to the hospital, because it would be all over the media."
Our People Magazine came yesterday, but I haven't read it yet. I do think the Bahamas was lenient overall about her drugs and is why she chose to locate there for the babies birth.
