Our kids are 12 and 10.
We limit "screen time"; we limit book-time to a lesser extent.
DH watches the morning news and the kids may glance at it during breakfast. They may also read a book or newspaper during breakfast.
During the week:
After school, they do their homework & practice music. If their homework involves needing the computer (writing a report, or practicing some maths online) then they can access for 45 minutes to an hour. Other than that, they can read books or play w/ non-electronic stuff. They may listen to CDs on their CD players in their rooms.
They may not read at the supper table unless it's special treat or they are eating by themselves (e.g. DH at t'ai ch'i practice, DS and I ate already & DD comes home late because of hockey practice).
They can watch the evening news w/ us and sometimes if there is a good show on TV (usually a nature program) they can watch before bed.
We usually let them read in bed until about 9 or 9:30 but then turn off the lights, because they have to wake up early for school and need their sleep for good health.
On the weekends - We allow them to watch a DVD in the morning while DH and I sleep in past 7am. They usually get some screen time (either computer or DVD or TV) in the afternoons - especially if the weather is bad. We let them play Runescape and watch some things like "Avatar the air bender" (or whatever it's called) on the computer.
We do not subscribe to Disney or Cartoon network. We do have Discovery Science, Animal Planet, etc. We do not have an Xbox, Xcube, PSP, Wii, or other electronic games. However, DH does have some games on his "Palm" and DD has a few games on her phone, but we try and limit those.
When "Project Runway" was on during Saturday nights, w let them watch it with us.
We have 2 lap-tops and 1 TV - but the kids prefer the newer lap-top.
