I don’t have a good idea about her abilities at all. Seems like we first heard she was non- verbal, now we hear she speaks two languages. We hear she has trouble walking, but she’s learning to ride a bike at school. She can’t do conceptual thinking, but she loves to tell silly jokes and was excited about going on vacation. She doesn’t leave her mom’s side, but she goes to school, which presumes she’s around other people. All a little confusing. It seems like she could’ve gone off on her own, but I can’t imagine how she would’ve gone into the forest.
I also can’t imagine a sibling watching her go out a window without yelling to the parents.
