It turns out that D4 really does want her mom by her side while she does her homework that night. I guess D4 wants some attention from her mom. I spoke to W about that incident and she immediately became defensive. She said she did not teach D4 to behave that way. MIL on the other hand was very apologetic. What!? I did not accuse them of anything. Just shared what happened that night.
She maybe feels she is to blame somewhat so she becomes defensive, quite normal for most people. MIL might feel slightly responsible because her daughters actions may have contributed.
When she becomes defensive and you are not accusing her, calmly state what you just said to us in that you were just sharing the event with her.
