DS1 is 6. Whilst he can talk in a perfectly normal voice, often at home he talks in a very loud voice. He also gets angry quickly and then shouts a lot. It infects DS2 (2) and then they shout at each other. I just can't stand the noise! It seems silly to shout 'stop shouting' when that means I am shouting too but I need a quick way to stop it otherwise it escalates.
Help?
I spend a lot of time saying 'use your talking voice' but it never seems to get through.
