I guess that all parents should anticipate their children fighting for numerous reasons, despite the fact that I hope that we all wish it wouldn’t happen at all.
I can’t prevent them from doing it 24 hours a day unless I never turned my back to either of them. My youngest is sensitive & has the worst time getting teased by his older sibling & sister. I have lectured the older 2 on countless occasions that their sibling isn’t their jester or source of entertainment. If either of them want to tease, they can tease each other & then we’ll see who’s ganging up on who. Occasionally they’ll argument over the remote to decide what gets shown on cable in the living room, despite them all having a cable in their rooms. Other times they’ll war over what games they play when they’re outside with their friends. Recently I caught them messing with the temperature control for the central Heating and A/C system. Each of them was trying to set the temperature in the apartment to a peculiar studying, which was forcing the cooling system to turn on & off repeatedly. After I found them doing it again following my warning to get them to stop, I finally put a plastic lock box over the temperature control so no 1 however myself & my spouse can access it to change the temperature in the house. Not only is it bad for them to mess with the Heating and A/C proposal without asking, it could also lead to premature destruction to the heating & cooling system. Now that the central Heating and A/C proposal temperature control is covered, they cannot argument over it any longer.
