Comfort others, it is best not to mention those things, because that is their family affairs, you don't know, if you comfort them, it may become more and more difficult to end. You can tell more jokes, or just accompany her quietly, take her shopping, eat and so on.

It is the most sensitive thing for a stepmother to scold her children. Because the child is still young, many things don't understand and can't be separated. What adults say is right or wrong. If the stepmother scolds her for her own good, she actually loves her. But for a child, all she hears is the rumor that her stepmother will not love those children who are not her own, so as long as she says a few words about herself, she feels that her stepmother hates herself.

You can try to ask her, don't make any comments, just listen to her whisper. Let it out.
