there's a wonderful article about Dani and what she suffered called "the girl in the window" if anyone is interested. what she went through is truly horrific, and I don't want to equate the level of abuse she suffered to Abbie, but I do agree that some of their affects are very similar - both developmentally toddlers in older bodies.
that video really reminds me though of those old vlogs from when they all went to visit Asa's family. his mom and step-dad live on a farm and I think Abbie would really do well in an environment like that. I know they've said repeatedly that living in the country isn't viable because of the lack of services (though isn't she already down to just one ABA session a week?), but she seemed like in an environment like that - lots of fresh air, open space to walk around in, simple tasks like collecting eggs or carrying baskets, would be really good for her.
