it is a bad influence....you should take it away....they will not whine forever....and if they do bust their you know what and give them something to whine about....good luck buddy.
Just sitting in front of TV and not learning anything or gaining physical exercise is a waste of their time. One or two cartoons are enough per day. No MTV ever. No going to friends' houses where they'll watch the blocked shows. Give them more constructive things to do. Buy them a tent and an extension cord for a fan. Monopoly and Uno. Lots and lots of snacks. They'll spend hours out there having fun--without TV.
Maybe you shouldn't block it you could just tell them there are certain shows on MTV that they can't watch. There are some pretty stupid shows on MTV lol
Cut your tv down to basic cable and MTV won't be an option. When they whine tell them they can take over the bills if they want it to change. Or just restrict tv time and then if they choose to use their time on the stupid programs at least they won't be watching them all day long; you'll save at least a few brain cells that way
I'm sure your kids think the shows you watch are stupid too certain tv show won't kill brain cells just let them get through the phase and it'll pass...
