They're treating her like a real kid.

Well.. shes behaving like one so she's treated like one. It was already explained that one of the aftermath were that she would behave mentally like a child for the time being

i mean there is nothing wrong with that, im old, have my house and car etc, but my parents still treat me like their baby. My dad prepares me food and my mom spoils me with my favorite chocolates. Literally nothing wrong at the moment.
