The article I posted last night, I think from the Star right after she died said they had information that the baby and a nurse were also there. Speculation I guess since no one has been id'd yet unless the HR tapes show them.
Just on instinct I don't think they took the baby with them to Florida. I don't think Anna ever bonded with Dannielynn -- if she had I doubt whether they'd have given the baby meds so that she wouldn't cry and wake them up.
Anna was completely selfish. I saw her reality show and although I don't doubt that she "loved" Daniel, it was a very seductive and selfish love.
She was simply incapable of empathy and nothing I've read or seen of her could convince me otherwise.
