I don't know if it will help any but I thought I would share what DH and I have done with our child(ren)!

From the moment James was born (nearly four years ago) I ceased watching all daytime television (save a bit of sport now and then).

When he turned two we decided to allow him to watch TV but we wanted to limit it so we decided he had to "earn" his TV time. Each day, if he has no time outs then he earns two stickers that he puts on the calendar at bedtime.

On Saturday night, if he has collected at least 10 stickers then he can watch a video after church on Sunday.

It works well.

Obviously there are exceptions to the rule - when I was sick one day I let him watch a DVD repeatedly as it meant he would sit quietly on the lounge. Also when he is sick he gets to watch DVD's and we do allow him to watch a bit of sport when something special is on so he has been cheering the tennis right along with me the past two weeks!

Not sure if this helps at all - but thought I would add my thoughts...
