It all starts off nice and calmly. I ask the DC (5 and 7) if they can do something in a normal speaking voice. They carry on talking loudly to each other, in whatever game they are playing, and I am not heard. I ask them to stop talking while I talk. It doesn't happen. Repeat during the day 100 times. They end up doing exactly what I have asked them not to do, and not what I have asked them to do. = SHOUT. I am not shouty, but the repetitiveness of this ordeal makes me just want to cry sometimes!
The second issue is that there is no threat or punishment that I can carry out that actually means anything to them, or that they care about.
I would love some advice please.
