I have always been pretty strict on how much TV my kids watch. Hannah is allowed to watch two shows after her schoolwork and chores are complete.
“Mom, I’ve been thinking about watching 3 shows now.” – very grown-up sounding, as if this is her decision.
“Mmm-Hmmm, Honey” (head in the refrigerator looking for apple juice for Ellie)…”Wait, why would you watch 3 shows?”
“I’m older and so I decided I need three now.”
Pouring the juice now, I think, “I can work this to my advantage”.
I nonchalantly mention that, gee, I would trade off an extra TV show for an extra chore…
She agrees, mentioning how she is willing to dust. I mention how the dishwasher needs unloading.
Really, it is a lesson on the concept of free enterprise. I have something she wants and she can provide a service I want.

3 sounds fair to me…especially if you get a bit of extra help…smart girls…MIMI
