My wife was very angry and took it out on her two-year-old son. What if her son is particularly noisy?

When your wife is upset, you should stall her son who is particularly noisy, take him out to play or go to the balcony or other room, as long as you don't let your son interfere with your wife, and at the same time, you can educate your wife to calm down when she encounters something. Children are not sensible, and adults can tolerate her more; Educate your son to be considerate of the feelings of adults, be obedient, don't patronize himself, and let him develop the habit of thinking of others.
