N.B.
I do home childcare and we only have very limited TV time (we love sesame street, but even that is a partial show thing and not every day).
We often have the radio on (holiday music now), but I have many kids CD's. They just play. I am a play-based facility and we shoot from the hip most of the day, while following a schedule for meals/snacks and naps. When things get out of hand, boredom sets in and might become naughtiness, then I change things up and direct the play by bringing out a new item (Lego's, trains, puzzles, do a dancing game, some new books, or do a cooking or art project).
They help me set lunch up, clean up...we practice cutting and tearing paper, sorting any and everything (early math skills)..they love helping me fold the hundreds of small washrag size towels we go thru each day (for washing and for single use hand drying all day long)...its a great way to teach them domestic skills and also math skills...whole, half and a quarter..as they fold them up! They have notebooks to write in with a pencil (works on holding a pencil and a few seconds or minutes of "writing").
Simply do not make the TV available. Its hard, but they learn quickly to be imaginative. I have only 1 large toy that makes noise in my whole daycare (its a freestanding playhouse door thingy..fisher price...makes doorbell noises and such)...everything else in here is pretty simplistic stuff...building toys, play kitchen a big kid size classroom table for doing puzzles, building, setting tea parties, etc. We love the table and use it for everything!
Good luck in going TV free..or TV-limited!
