Quote #4
She worked at her sewing with energy, listening to the children, and her anger wearied itself, lay down to rest, opening its eyes from time to time and steadily watching, its ears raised to listen. (1.80)
Even though being active with her sewing seems to calm Elizabeth down, she still seems mighty agitated.
Quote #5
The mother looked down at them, at the brown silken bush of intertwining curls in the nape of the girl's neck, at the little black head of the lad, and her heart burst with anger at their father who caused all three such distress. (1.89)
In addition to being frustrated on her own account, Elizabeth is angry that Walter's drunken carousing/repeated absenteeism is harming his children. Her dissatisfaction with her lot in life is just seeping out of every thought and reaction.
