DS shouts as loud as he can and it goes right through me. When we're out and he shouts I tell him if he continues we will go home. If he's outside I say we will have to go inside, this works.
However when he's in the house what can I do. Shouting at him is a bit counter productive but sometimes he shouts so continuously loud and I end up doing it.
It started with his Baby sister as she's a shouty baby so he started copying her and now it's ingrained in him
