OK, I dont have a TV in my house full stop.
My parents on the other hand have a mahooosive one, however during ramadan the cover it with a sheet and tell the kids it's not working. amazingly the kids have never pressed for further detail, as I have filled the house with toys.
In my house we have a toy room where all the toys are kept, as my girls have gotten older they have sorted the room so one corner is dedicated to all things dolly, ie castles, horses, leafy bowers, prams, cots,the million and one princess and abaya clad dollies etc, one corner is crafts, so plasticine, paints, pens, pencils knitting and weaving kits, and one side has giant plastic boxes with board games, also one whole wall is dedicated to books, I've split the books out according to reading level so both girls can easily get to books they can read (actually my little sister did!).
The rule is at the end of the day everything is put back in its place, or I chuck it! and the toys don't go in any other room (the latter rule is often bent...)
The toys have obviously changed as the girls have grown older, but this was roughly what I had to begin with.
As it happens because of this my girls are able to entertain themselves really well...or perhaps the fact that I utterly neglect them means they got bored and occupy themselves with the toys....
It doesn't seem to bother them that we dont have a TV, altho we do watch programmes on the computer ocassionally, but mostly they entertain themselves.
My point I think is, throw a sheet over the TV, tell them TV is asleep and put all their toys together and leave them to it, you may be surprised. I personally cannot do the hands on entertaining kids continuously thing that most amazing mamas can!
