I think she has always known that Khushi is strong mentally and does not need her support, so did not refer to her as a child till now, neither did anyone else. But yesterday when in the midst of everything she was comforting her mother and saying that Arnavji will be coming any moment now, I looked at her face. As if she was shocked that Khushi is behaving like a child, and so she referred to her as her Bachchi who once more needs her.
