I have a love hate relationship with screen time. Because they want it ALL THE TIME, managing my children's access to it is extremely aggravating. But since they love it so, we are all beholden to it; they need their fix, and I need my threat.
In matters of discipline, you have to find the thing that most efficiently brings your charges to their knees. For my family, screen time is the closest thing we've got to a magic bullet. Screen time is my sword and my shield, and I do not hesitate to smite my kin at will. The Lord may giveth, but I taketh away.
Its power is so awesome that after months of all sorts of attempts at positive behavior modification, the promise of television may ultimately be the thing responsible for toilet training Sacha. If it proves successful, I will have no choice but to turn it into a shrine and make daily offerings.
And so while I sometimes contemplate banishing screen time altogether because I don't want to hear someone ask me one more time if they can watch tv/play Wii/use their iPod, in reality, what I really need is duplicate electronic devices, so that once I've taken away the privilege, I have a spare handy so I can do it all over again.
